This Saturday, The Mann promises to be the place for great music. Nine time Grammy Award Winner and kick ass guitar player Bonnie Raitt and recent inductee to the Blues Hall of Fame and all around bad mamma jamma, Taj Mahal, will kick off their summer tour - the Bontaj Roulet Project - by bringing their smoky and delicious blues to the Philadelphia music scene. Backed by their individual bands, the concert will feature both artists as individuals, each playing their own full set and will end the night with a blow-out collaborative performance.
