What Is a Session Musician? 3 Maps, 43 Releases, 1972 to 2026
A session musician is a player hired for a recording rather than a member of the band, credited on the sleeve for exactly what they played. Across three of my discography music maps, 43 releases between 1972 and 2026, those hired players outnumber the band on nearly every record.
The reason I keep coming back to them is that a tube map answers a question a credit list cannot: how long did they stay? A band member and a session player look identical on a sleeve. On a map, one line runs the width of the print and another stops after one station.
The Three Maps in This Piece
- Steely Dan, 9 studio albums, 1972 to 2003, 127 credited names. The longest session line belongs to Victor Feldman, on 7 of the 9.
- R.E.M., 15 studio albums, 1983 to 2011. The longest session line belongs to Scott McCaughey, on 6.
- Johnny Marr, 19 releases across eight acts, 1984 to 2026, 125 credited names. James Doviak and Jack Mitchell are on all six solo records.
All three counts come from my own research sheets, the ones the artwork was drawn from, and not from a streaming credit panel.
What Is a Session Musician on a Discography Map?
On my maps, albums are stations and every credited musician is a line. I do not draw band members and session players differently, because the sleeve does not either, and because the interesting thing is not the job title but the length of the line.
A one-off session player becomes a branch line, a short spur off a single station. Someone hired for three records in a row gets a line that runs through three stations and stops. And occasionally a session player's line outlasts the band's own, which is the shape I find most worth printing.
Victor Feldman Outlasted Two Steely Dan Members
Steely Dan is the band people reach for first when they talk about session players, and my sheet shows why. Donald Fagen and Walter Becker are credited on all nine albums. After them, the longest line on the print is not a band member at all.
Victor Feldman, a percussionist and vibraphone player, is credited on seven of the nine: the 1972 debut, then 1973, 1974, 1975, 1976, 1977 and a single percussion credit on Gaucho in 1980. Denny Dias reaches six. Jeff "Skunk" Baxter, who was in the band, reaches three. Jim Hodder, who was the drummer, also reaches three.
So on the printed map, the hired percussionist's line runs more than twice as far as the drummer's. That is not a trick of the layout. It is what the sleeves say.
Gaucho Credits 41 People, the Debut Credits 13
The Steely Dan count row reads 13, 19, 21, 22, 24, 37, 41, 30 and 22. I checked it against the grid in the first column, counting thirteen names on the Can't Buy a Thrill cell by cell, and it reconciled exactly, so I trusted the row for the rest.
That sequence is the whole story of a band turning into a studio project. Thirteen people on the 1972 debut, when they were still a touring group. Thirty-seven on Aja in 1977. Forty-one on Gaucho in 1980, the busiest station on the print, by which point the two names on the cover were surrounded by hired players three deep. Then a twenty-year gap and a return at thirty.
The Session Player Who Becomes the Band
The opposite shape turns up on the R.E.M. map. Scott McCaughey first appears on New Adventures in Hi-Fi in 1996, the year Bill Berry played his last album with the band, and he is still credited on Collapse into Now in 2011. Six stations. Bill Rieflin covers the last three. Neither was ever a member, and between them, they are the reason the post-Berry records still sound like a band rather than three people.
The Johnny Marr map does the same thing in a tighter space. James Doviak and Jack Mitchell are credited on all six of his solo columns, and Iwan Gronow on five. After twenty-five years of changing company across The Smiths, The The, Electronic, Modest Mouse and The Cribs, the map finally shows a stable group of lines running alongside his.
And the Ones Who Play on One Track
Most session credits are not careers. They are an afternoon.
| Player | Credited for | Stations on the map |
|---|---|---|
| Victor Feldman | Percussion and vibraphone, Steely Dan | 7 of 9 |
| Scott McCaughey | Guitar and keyboards, R.E.M. | 6 of 15 |
| James Doviak | Keyboards and vocals, Johnny Marr solo | 6 of 6 solo records |
| Sherlie Matthews | Backing vocals, Steely Dan | 5 of 9 |
| Elliott Randall | The guitar solo on "Reelin' In the Years" | 3 of 9 |
| Snooky Young | Flugelhorn, Can't Buy a Thrill | 1 |
| Steve Berlin | Horns on "Fireplace", R.E.M. | 1 |
| Karl Bartos | Keyboards on Raise the Pressure | 1 |
Snooky Young is the one I think about. A flugelhorn on a 1972 debut, one credit, one short spur, and on a sheet of 127 names his is as visible as anybody's. That is the argument for drawing credits rather than listing them.
Sizes and Paper
These three maps are printed the same way. A3 is 420 x 297 mm, A2 is 594 x 420 mm and A1 is 841 x 594 mm, every size unframed or ready to hang in a black wood frame, and A1 is the size at which a forty-one-name station separates into readable lines.
Three inch formats are sold alongside the A sizes rather than as conversions of them: 16 x 12 in, 24 x 18 in and 36 x 24 in. Every print is a Giclée on 230gsm premium acid-free matte fine art paper, with the full detail on the print and frame specification page.
The map with the most session players on it
Nine studio albums, 1972 to 2003, and 127 credited names, with 41 of them on Gaucho alone.

Session Musician Questions, Answered
What is the difference between a session musician and a band member?
A band member is part of the act and usually appears on every record it makes. A session musician is hired for a particular recording. On my maps they are drawn identically, so the only difference you can see is how far the line runs.
Do session musicians get credited on albums?
Usually, but not always, and the detail varies enormously. Some sleeves name the track and the instrument, as Steely Dan's do. Others give a name and nothing else. I map whatever the sleeve credits, and where it credits nothing I cannot draw a line.
Which album has the most session musicians on it?
Of the three maps here, Gaucho in 1980, with 41 credited names against the 13 on the 1972 debut. The next busiest are Aja at 37 and Two Against Nature at 30.
Are session musicians on the map, or only the band?
Everyone the sleeve credits with playing something, which on most of these records means the session players outnumber the band several times over.
What is not on the map?
Compilations, soundtracks and almost all live albums are left off by editorial rule, so the Steely Dan and R.E.M. maps are studio records only. The Johnny Marr map carries one deliberate exception, the 2001 7 Worlds Collide, which was recorded live and sits there as half of that project's pair. Anything released after the artwork was drawn is left off, and so are producers and engineers with no playing credit.
