Ode to O is the second release by the OGJB Quartet, a cooperative group that features four longstanding leaders in modern improvised music, saxophonist Oliver Lake, cornetist Graham Haynes, bassist Joe Fonda and drummer Barry Altschul. Each group member is a composer in his own right and a master on his chosen instrument. The new release, which follows highly acclaimed Bamako released in 2019, again features compositions contributed to the recording by all of the group's members as well as two collective improvisations. The album is named after Barry Altschul's composition dedicated to the late Ornette Coleman.
