Buck's style of guitar playing is simple and yet distinctive. He makes wide use of open strings while chording to create chiming and memorable pop melodies. His sound, especially on mid-period R.E.M. albums that saw the band breakthrough to international popularity, has been associated with
Rickenbacker guitars, particularly a black model 360. However he has also used a wide variety of other instruments as the group has continued to experiment and develop. On some more recent R.E.M. releases, the guitar has been noticeably less prominent, often turned down lower in the mix in deference to the band's increasing use of synthesizers, strings and other atmospherics.
Buck has produced many bands, including
Uncle Tupelo, The Fleshtones, and
The Feelies, among others. Buck also has made contributions on many other musicians' albums, including
The Replacements, Robyn Hitchcock, and several
Eels albums. Buck also coproduced the 1992
Vigilantes of Love album,
Killing Floor, with songwriter
Mark Heard. Along with R.E.M. sideman
Scott McCaughey, he has been a partner in
The Minus 5, for which he plays bass, and has been a member of the instrumental band
Tuatara. Additionally, In October
2005, he joined R.E.M. studio drummer
Bill Rieflin and four others in forming an improvisational performance band called Slow Music. His voice can be heard on one R.E.M. song: "I Walked With a Zombie" from the
Roky Erickson tribute album "Where the Pyramid Meets the Eye." He also recorded an EP with Keith Streng of
The Fleshtones as Full Time Men in 1985. In 2006, Buck toured with
Robyn Hitchcock, McCaughey, and Rieflin as lead guitarist for
Robyn Hitchcock and the Venus 3 in the wake of the band's first release,
Olé! Tarantula.
Buck has contributed liner notes to a number of compilations, reissues, and special editions, both of R.E.M.'s own material (the best-of compilations
Eponymous and
In Time, and the special edition of
New Adventures in Hi-Fi) and of other artists' work (such as the
Beach Boys' Love You).
