LITTLE ROCK, Ark. (AP) — Alligator Records says U.S. bluesman Michael “Iron Man” Burks has died after collapsing at Hartsfield-Jackson Atlanta International Airport on his return from a European tour. He was 54.

The record label says Burks collapsed Sunday. He was pronounced dead at an Atlanta hospital. A spokesman for the record label says Burks died of a heart attack.

Burks and his father built Camden's Bradley Ferry Country Club, a 300-seat juke joint that hosted blues and R&B performers in Arkansas.

He released three albums with Alligator Records and headlined blues festivals worldwide.
