Frogwings began as an Allman Brothers/Aquarium Rescue Unit side project in 1997, with Edwin McCain as the lead singer. The band ran off five gigs in seven days in late May 1997, and the jazz/rock/calypso/metal fusion began. Founding members Butch Trucks [drums] and Jimmy Herring [guitar] were joined by the Burbridge brothers, Kofi [flute] and Oteil [bass], as well as Butch's nephew Derek [guitar/, and band and percussion-mate Marc Quinones. The successful May run was followed by a two-week trip up and down the East coast in December, and this run cemented Frogwings as a permanent part of the Allman Brothers Band sideshow.
