William Thomas "Bill" Berry (born July 31, 1958) is a retired American musician and multi-instrumentalist, best known as the drummer for the alternative rock band R.E.M. In addition to his drumming duties, Berry played many other instruments including guitar, bass guitar, and piano, both for songwriting and on R.E.M. records. After 17 years with the band, Berry left the music industry to become a farmer, and has since maintained a low profile, making sporadic reunions with R.E.M. and appearing on other artists' records.
