Tube Map Art Explained: 70 Maps, Albums as Stations, Credited Musicians as Lines
Tube map art is information design that borrows Harry Beck's 1931 London Underground diagram and applies it to subjects other than railways. On my 70 music maps, each studio album is a station and each credited musician is a named line running through the records they played on. The shape those lines make is the artist's working life.
At a glance: Tube map art applies the structural logic of Harry Beck's 1931 London Underground diagram, ordered lines, evenly spaced stations and clean interchanges, to subjects beyond transport. In the music discography maps I research and draw at mikebellmaps.com, a studio album is a station and a credited musician is a coloured line. The Beatles map carries 13 releases between March 1963 and May 1970 with 139 credited lines through them, George Martin running all 13 stations and Andy White appearing once, on the 1963 debut. Prints are held at the V&A David Bowie Centre, London, and the Bruce Springsteen Archives at Monmouth University.
How to read a music map: the four elements and what each one means
The grammar is identical on every map I draw, which is the point of using a transit diagram at all. What varies is the shape the data makes, never the system. The examples below come from the Beatles research grid, because it is the one most people already know the names on.
| Element | What it represents | Worked example |
|---|---|---|
| A coloured line | One credited musician: band member, session player or guest | George Martin runs all 13 Beatles stations, on credited musical input rather than production |
| A station | One studio album, placed in release order | Revolver, 5 August 1966, carries 26 credited lines |
| An interchange | The point where several musicians' lines converge on one record | Magical Mystery Tour, November 1967, is the busiest on the map at 74 lines |
| A branch line | A one-off contributor, spurring off and stopping | Andy White appears once, on Please Please Me in March 1963 |
If you want that walked through on a printed map rather than in a table, how to read a music map goes through one station at a time.
Where the tube map art style comes from
Tube map art begins with one of the most influential pieces of graphic design of the twentieth century. Harry Beck drew the London Underground diagram in 1931 to solve a specific problem: how to show a tangle of intersecting routes so an ordinary passenger can read it in seconds.
Beck's move was to throw away geographical accuracy and keep only the lines, the stations and the connections between them. The result is not a map of where things are, it is a map of how things connect. Because the style describes relationships rather than geography, it carries anything that behaves like a network. I have used it for film plots, where characters run as lines through scenes, as on the Back to the Future plot map art print. But the subject it fits best, and the one I have built the catalogue around, is the recording history of a band.
Why a discography suits the format so well
A discography suits the format because a discography is a network, not a line. It is tempting to picture a career as a straight road from debut to final album, but that is never how it works. Musicians join, leave and return. Guests appear for a single track. The real structure is a web of relationships stretched across decades, and a web is what Beck's diagram was invented to clarify.
From the patterns I have mapped, the careers with the richest networks make the most rewarding prints. David Bowie, whose reinventions brought fresh collaborators each era. Fleetwood Mac, with its shifting line-ups. Steely Dan, built around Walter Becker and Donald Fagen with a rotating cast around them. Deep Purple, where the Mark line-up changes arrive on the page as visible clusters.
That is why the format speaks to people who read liner notes for pleasure. A collector who knows the records is the person who will trace a session player from one album to the next, or spot the guitarist who quietly shaped three in a row. A wall of album covers cannot show that. The Deep Purple discography art print and the Crowded House discography art print are two ends of one idea: one dense with turnover, one built on three lines that mostly hold.
What a music map means, in plain terms
People arrive here searching for what a music map actually means, so here it is without the design history. A music map is a diagram of who made a body of recorded music, drawn in the visual language of a transit network. It does not rank the albums, review them or chart their sales. It answers one question: who played on what, and where do those people overlap.
That narrowness is deliberate. The maps carry studio albums only, so live albums, compilations and soundtracks are left off by editorial rule, and a few carry a named exception where the artwork always did. what gets left off a discography map sets out every one of those decisions.
What a music map costs, and in what sizes
Every print is a museum-quality Giclée on 230gsm premium fine art paper, textured matte and archival acid-free, made to order. The maps are landscape and sold in three A sizes: A3 at 420 x 297 mm (16 x 12 in) for £35, A2 at 594 x 420 mm (23 x 16 in) for £45, and A1 at 841 x 594 mm (33 x 23 in) for £65. A3 is unframed only. A2 and A1 come unframed or ready to hang in a black wood frame, at £125 and £175.
Three inch formats, 16 x 12 in, 24 x 18 in and 36 x 24 in, are sold alongside the A sizes as separate formats rather than conversions of them, priced the same way. Both Beatles maps and the Levellers run A1 only, so their floor is £65. Across the rest of the range £35 is the lowest price, and how much a music map costs breaks it down size by size. Paper and frame detail is on the print specifications page.
How I research and design each one
The design is the easy part. The research takes the time. When I begin a new map I spend weeks on liner notes, label credits and session logs before a single line goes down in the layout file, because accuracy is the entire point of the piece.
I build each artist's history in a spreadsheet where every row is a credited musician and every column is a studio album, and a filled cell means that musician played on that record. That grid becomes the network of lines and stations on the finished print, so if the grid is wrong the artwork is wrong. The Beatles grid runs 139 rows against 13 columns. No AI is used at any stage, which is why a stock illustration will never appear on one of these pages, and it is the reason a map rewards every closer look rather than being decoration printed over an album cover. On why the printing standard matters as much as the research, what is a Giclée print covers the paper and the inks.
Where to see the full range
All 70 music maps sit in the music wall art prints collection, from the Beatles and Bowie to The Smiths, Queen and Nick Cave. The film plot maps collection carries the same logic across to cinema. For one map that shows what the format can do, the David Bowie discography art print is where I would start.
Tube map art: questions I get asked
What is tube map art?
It is a style of information design that borrows the look and structural logic of Harry Beck's 1931 London Underground diagram and applies it to a subject other than a railway. In my maps the subject is a recording career, with albums as stations and credited musicians as lines.
What does a music map show?
It shows who played on which records across an artist's studio catalogue, and where those people overlap. Each credited musician is one named line, each studio album one station, and a musician on a single record a short branch line.
How much does a tube map art print cost?
From £35 for A3 unframed, rising to £45 for A2 and £65 for A1. Framed in black wood, A2 is £125 and A1 is £175. On the A1 only maps, both Beatles prints and the Levellers, the floor is £65.
Who designs the maps?
I do. I am Mike Bell, and I research and draw every map myself. The David Bowie map is held in the permanent collection at the V&A David Bowie Centre in London, and the Bruce Springsteen map at the Bruce Springsteen Archives at Monmouth University, who called it "truly amazing" when they made contact in November 2020.
What is not on a music map?
Live albums, compilations, soundtracks and non-album singles are left off, because the maps carry studio albums only. A handful carry a named exception where the artwork always did, and anything released after a map was drawn is not on it until it is redrawn.
Picking one
If you know whose records someone has worn out, the map almost picks itself. If not, the gift card for music fans lets them choose their own, usually the better outcome with 70 maps on the shelf.
