Brad Barr will lend his guitar (and himself) to the next three performances by the Benevento Russo Duo. Joe Russo has been composing new material on the guitar as of late and Barr will appear on a number of those songs. The Duo recently returned from a west coast tour where Tom Hamilton (Brothers Past) appeared in such a role and now the Slip guitarist will try his hands at the material. Barr will do so during the band’s appearances at Higher Ground (Thursday), Bearsville Theater (Friday) and Pearl Street (Saturday).
