Timothy W. "Tim" Alexander (born April 10, 1965 in Cherry Point, North Carolina) is an American musician, best known as the drummer for the rock band Primus. Tim played on the Primus recordings Suck on This to Tales from the Punchbowl, before leaving the band in 1996, only to rejoin in 2003 for the EP Animals Should Not Try to Act Like People. He was a member of, and toured with, Primus from early 2003 until approximately 2009 when he was replaced by Jay Lane. Although Alexander has been quoted saying he was originally inspired to become a rock drummer by legendary drummers like John Bonham, Neil Peart and Shaun O'Connor, Primus guitarist Larry LaLonde claims Alexander's drum beats are mostly influenced by African Jùjú music.
Prior to joining Primus, he played and recorded with Major Lingo, which at the time was a ska-based rhythm band that featured a lap steel guitar as the lead instrument, played by Tony Bruno. When Major Lingo toured through the Bay Area Tim met members of Primus and would go on to remain there trying out for the band.
