Full Tilt Boogie Band was a Canadian rock band originally headed by guitarist John Till and then by Janis Joplin until her death in 1970. The band was composed of Till, pianist Richard Bell, bassist Brad Campbell, drummer Clark Pierson, and organist Ken Pearson.
In its original late 1960s incarnation, the Full Tillt Boogie Band (the two "Ls" being a play on the spelling of Till's last name), Till fronted the group as a side project from his usual gigs as a New York City studio musician. Like Till, the other members of Full Tillt were Canadians, mostly hailing from Stratford and Woodstock, Ontario, Canada.
When Joplin's management convinced her to discard Big Brother and the Holding Company as her backing band, her record label put together a new group of musicians for her. This group, dubbed the Kozmic Blues Band, consisted of Till and several other Full Tillt Boogie Band members — all studio musicians whom her label was familiar with and felt were reliable — plus a horn section. Joplin was not happy touring with some of the group members, however, feeling them to be too "square", and the disappointing reviews of their 1969 album I Got Dem Ol' Kozmic Blues Again Mama! led her to scrap everyone in the group except Till.
