Waronker's first professional project was the alternative rock band Walt Mink, which he helped form while attending Macalester College in St. Paul, Minnesota, in 1989. The band's name was taken from that of a former psychology professor at Macalester.[3] He played on their first two albums, Miss Happiness (1992) and Bareback Ride (1993).
In 1998, Waronker played drums on two songs ("Bled White" and "Bottle Up and Explode!") on Elliott Smith's XO album. He also appeared on "Stupidity Tries" on Smith's next release, 2000's Figure 8.
R.E.M.
In October 1997, R.E.M.'s drummer Bill Berry left the band in pursuit of a quieter life. Seven months later, as R.E.M. rehearsed in Athens, Georgia, for a tour in support of that year's Up album, Waronker entered the band and toured with them in support of the tour. His first performance with R.E.M. was in Washington, D.C., at the Tibetan Freedom Concert at RFK Stadium.
Between 1998 and 2002, Waronker toured with R.E.M. and appeared on two albums, 1998's Up and 2001's Reveal.
