Michael Curtis has 2 Delaney & Bonnie and Friends concerts.

The husband-and-wife duo of Delaney & Bonnie Bramlett created some of the most distinctive and unique music of the early '70s, but their alchemical sound -- equal parts blue-eyed soul, blues, country, and gospel -- was often marginalized by the attention instead paid to the contributions of their famous "friends," including rock icons like Eric Clapton, Duane Allman and George Harrison.
