ZZ Top brought their Antenna Tour to the War Memorial in Rochester, reuniting with a city that had seen them through decades of touring. The Texas boogie trio had survived the synthesizer era of the ’80s and were returning to their blues-rock roots on Antenna — a back-to-basics move that longtime fans celebrated. Billy Gibbons’ guitar tone and that unmistakable rhythm section filled the War Memorial with the kind of big, swaggering rock that ZZ Top had always been built for.
