Bloodrock 2 was their most successful album peaking at number 21 on the Billboard Pop Album Chart in 1971, on the strength of their single ” D.O.A. “, which reached number 36 on the Billboard Hot 100 chart on March 6, 1971. “D.O.A.” also gave the band considerable regional exposure throughout the Southwest and West, particularly in Texas and Southern California. “D.O.A.” was the band’s most well-known and well-remembered single. However, some radio stations would not play the song because of its explicit, gruesome description of fatal plane crash injury and the use of sirens, the latter out of concerns that the siren sound would confuse motorists. The motivation for writing this song was explained in 2005 by guitarist Lee Pickens. “When I was 17, I wanted to be an airline pilot,” Pickens said. “I had just gotten out of this airplane with a friend of mine, at this little airport, and I watched him take off. He went about 200 feet in the air, rolled and crashed.” The band decided to write a song around the incident and include it on their second album.
