Although his first solo album is remembered for containing the immortal pop hit "Brown Eyed Girl," Blowin' Your Mind! is actually a dry run for Van Morrison's masterpiece, Astral Weeks. Songs like "Who Drove the Red Sports Car" look to that song cycle, even as "Midnight Special" nods to Morrison's R&B past. But it is the agonizing "T.B. Sheets" — all nine-and-three-quarters minutes of it — that dominates this record and belies its trendy title and pop association. "T.B. Sheets" takes the blues and reinvents it as noble tragedy and humiliating mortality. It is where Van Morrison emerges as an artist. (Blowin' Your Mind! was superseded by Bang Masters, which contains all of its tracks except "He Ain't Give You None," presented in an alternate take, plus Morrison's other recordings for Bang, in 1991.)
