Roots of YU Grupa

Korni Grupa was a Yugoslav rock band formed in Belgrade in 1968. Launched and led by—as well as named after—the keyboardist Kornelije Kovač, the band was one of the first Yugoslav rock acts to achieve major mainstream popularity in the country, and often considered the very first Yugoslav supergroup. Since their dissolution, Korni Grupa gained significant retroactive acclaim as one of the most influential bands in the history of rock music in Yugoslavia. The band additionally used the Kornelyans name during a short-lived commercial foray outside of Yugoslavia in an attempt at breaking into the international market with an English-language album.

The Allman Brothers Band was an American rock band formed in Jacksonville, Florida, in 1969. Brothers Duane and Gregg Allman founded it with Dickey Betts, Berry Oakley (bass), Butch Trucks (drums), and Jai Johanny "Jaimoe" Johanson (drums). Subsequently based in Macon, Georgia, they incorporated elements of blues, jazz and country music and their live shows featured jam band-style improvisation and instrumentals.
