Taking center stage at the head of a rocking roots band, Eric Clapton infused his ‘70s performances with a righteous fire that occasionally bests the studio originals, as this collection proves. The insistent riff of “If I Don’t Be There by Morning” is more alive and raucous, while the presence of a breathless audience lends greater weight to the scathing, slow blues of “Ramblin’ On My Mind” and a communal glow to the folky warmth of “Can’t Find My Way Home.”
