Tired of his then-middling music career, Trucks pondered going back to school to study mathematics. In 1969, he was invited to join a new project headed by Duane Allman, who had secured a record deal with Atlantic Records. Allman introduced Trucks to Jai Johanny Johanson (Jaimoe), who would also be a drummer in the band. Together, the two developed a rhythmic drive that would prove crucial to the band. Trucks laid down a powerful conventional beat while the jazz-influenced Johanson added a second layer of percussion and ad libitum cymbal flourishes, seamlessly melded into one syncopated sound. Said founding member and co-lead guitarist Dickey Betts of Trucks' addition to the original band lineup, "When Butch came along, he had that freight train, meat-and-potatoes kind of thing that set Jaimoe up perfectly. He had the power thing we needed." The group became the Allman Brothers Band, who began touring heavily and released their first, self-titled album, later that November. Trucks continued to record and perform with the Allman Brothers Band until they disbanded in 2014. From 1982 to 1984, during one of the periods in which the Allmans were broken up, Trucks was part of the group Betts, Hall, Leavell and Trucks. Along with Allman Brothers band members Johanson, Betts and Gregg Allman, Trucks was a plaintiff in a lawsuit against UMG Recordings. The suit, initiated in 2008, sought $10 million over royalties from compact disc sales and digital download services such as Apple's iTunes. Trucks saw the license given to users for downloads as legally unsound. Trucks embraced Internet technology for the group and planned to use Moogis.com (now defunct) to make the Web a "real venue" for the Allman Brothers and other jam bands. In the Brothers' later years, he helped connect them to the extended jam band scene. In 2013, he formed the Roots Rock Revival master camp experience. In 2015, Trucks performed at two festivals with a band billed as Butch Trucks & Very Special Friends. This band evolved into a band called Les Brers which was led by Trucks and also featured other former Allman Brothers band members including his longtime drumming partner Johanson. He also performed with a band called Butch Trucks & The Freight Train Band. Trucks had a long interest in philosophy and literature. In 2005, The New York Times Book Review published a letter from Trucks criticizing writer Roy Blount, Jr.'s reference
