Some people let adages and axioms slide off their shoulders. Others recognize their essential wisdom and run with them. A sterling example of the latter is the Commotions, for whom the sage chestnut, “Go big or go home” acts as a kind of roadmap for navigating the way forward. The Commotions write epic, sparkling, uncommonly skilled jazzy, funky soul/pop that, depending on where you are on Volume II, conjure everything from Motown to Stax to Jake and Elwood. If this was the 1970s, The Sonny & Cher Show would be duking it out with Lola Falana to book the band for a marquee spot.
