Bobby Rush, at age 82, is at the peak of his powers as a singer, songwriter, harmonica player, and, above all, an entertainer. Porcupine Meat features all-new compositions that range from the down-and-dirty funk of “I Don’t Want Nobody Hanging Around” and the playful double entendre of “Catfish Stew,” to the deep blues of “Got Me Accused” and the slippery R&B of the title track (about the charms of an otherwise malicious lover). Guest guitar soloists include Keb’ Mo’, Joe Bonamassa, and Dave Alvin.
