Tommy Castro's sixth release for the Blind Pig label, Painkiller, picks up where his 2003 set, Soul Shaker, left off. This time around, producer John Porter -- who has worked with Santana, Taj Mahal, B.B. King, and Buddy Guy -- positions Castro's Delbert McClinton/Southside Johnny vocal grit in front of a punchy horn section and rounds out the date with a few guest artists. Unlike many similar modern blues projects of good intentions but lackluster performances, the combinations on Painkiller never sound forced. In particular, the Albert Collins track, "A Good Fool Is Hard to Find," has Coco Montoya and Castro trading vocal jabs and guitar riffs, and Angela Strehli's passionate vocal on Freddie King's "If You Believe (In What You Do)" is likewise another highlight of this overall triumphant rock 'n' soul album.
