Bloodrock 2 is the second album by the Texas rock band Bloodrock.[3] It was released on Capitol Records in October 1970 and produced by Terry Knight. The album was certified Gold by the RIAA in 1990.[4] In early 1971, the gory extended track "D.O.A." became the biggest hit of Bloodrock's career when it was issued in shorter form as a single.[4] The motivation for writing the 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.
