There is more than one artist with this name:
1) Slapstick was a Chicago-based (many members were from Elgin, IL) ska/punk band active from 1993-1996, consisting of Brendan Kelly (vocals), Dan Andriano (bass), Dan Hanaway (trumpet), Matt Stamps (guitar), Rob Kellenberger (drums), and Peter Anna (trombone). They toured extensively and played endless shows in the greater Chicagoland area. They were signed to Asian Man Records. Reports exist that Slapstick turned down large amounts of money to sign to a major label, and instead broke up in 1996.
