Jeff Thacher

Jeffrey Thomas Thacher (born December 23, 1967) is an American musician, best known as a member of the vocal group Rockapella. A professional vocal percussionist (a practice also referred to as "mouth drumming" and related to the hiphop-derived beatboxing) and singer who emerged on the early contemporary a cappella scene in 1991, Jeff Thacher co-founded the Boston-based a cappella group Five O'Clock Shadow (aka FOCS) that year and went on to join Rockapella in 1993 as their full-time mouth-drummer. Thacher was a 1990 graduate of Berklee College Of Music's Music Production & Engineering program, and afterward spent several years in television & radio production when not performing

Vocal percussion, as a full-time occupation amidst a band or ensemble, was a fairly new idea in 1991, and Thacher performed as a tenor in Five O'Clock Shadow when not mouth-drumming. At that time, Rockapella was halfway through their stint on the children's television geography gameshow Where In The World Is Carmen Sandiego? on PBS(1991–1996) and had created several albums for the Japan-only record label For Life Records, as well as a soundtrack album for the Carmen Sandiego show. These albums had utilized individual computer-sequenced samples of mouth noises for their drum tracks. Rockapella sought to translate this approach organically to their live shows via a human performer, and after a search, Thacher got the job.
