Legendary glass cleaner, full-time tough guy, and part-time philosopher Charles Oakley once said, "If it ain't broke, don't break it." While the context in which he was giving a very Oak Tree take on an old adage seems lost to history, he may as well have been describing The Heavy's approach to making music. Now five albums into a career that dates back to 2007, the British quartet, adorned as always with some tasty horns, continue to get their rock/blues/soul/funk groove on with Sons. If that genre blend sounds like every bland jamband of the early aughts, The Heavy almost certainly would have been a festival mainstay at places like Langerado and 10,000 Lakes had they started a decade earlier. One distinction: this band can actually write a decent tune. So much so that The Heavy's songs have been featured in commercials, trailers, movies, and even video games. Sons falls in line with its predecessors as another perfectly fun, summertime album. Nothing to fix here.
