If Caruso lights a candle, Bread Zeppelin brings an inferno. The Led Zeppelin tribute powerhouse takes the stage and immediately raises the temperature several degrees, delivering a scorching set that makes abundantly clear why their reputation precedes them. Every riff is committed to with total conviction. The rhythm section hammers and breathes as one. The front of the amphitheater surges forward. This is not an imitation, it is an act of devotion performed with the technical ferocity the source material demands, and Boca Raton is left in no doubt that it has just witnessed something formidable.
