Famed saxophonist Ornette Coleman was treated for heat-related dehydration after he collapsed during his performance at the Bonnaroo Music & Arts Festival this weekend.
The 77-year-old Coleman, who is considered a pioneer of "free jazz," was taken to a local hospital Sunday and released later that night, said publicist Ken Weinstein.
Coleman won the 2007 Pulitzer Prize for music for "Sound Grammar," his first live album in 20 years. The recording features six new compositions and remakes of classics "Song X" and "Turnaround."
He received a lifetime achievement award at this year's Grammy Awards.
Conditions at the Bonnaroo festival, about 60 miles southeast of Nashville, were hot and dusty. One fan died and officials were investigating whether drugs or heat played a role.
