Birthday Blues, released in January 1969, was Bert Jansch's sixth album for Transatlantic. It's no surprise that the album sounds like a modified version of The Pentangle, as Bert was a member of the classic British folk/jazz/rock group at the time of this record's release. Additionally, Shel Talmy, who worked with the group (as well as The Who and The Kinks) produced Birthday Blues. To complete the circle, the record's rhythm section was Pentangle's: Danny Thompson on bass, and Terry Cox on drums. Jansch was the group's finest musician, and can still be a compelling writer and performer on his own.
