Before Taj Mahal and Ry Cooder became legendary electric guitar players with incredible, eclectic discographies, they were bandmates. In the mid-1960s, the two cut their teeth in an L.A.-based band called the Rising Sons. Though the group gigged relentlessly in the area, signed to Columbia Records and won some high-profile admirers, their sole album (recorded in 1965) remained unreleased until 1992. Now, 57 years later, Mahal and Cooder have reunited for a new album, Get On Board.
