Wiggins brothers Raphael and D’wayne and cousin Timothy Christian Riley possessed the rare capability of fitting into their ’90s R&B era while commanding an encyclopedic knowledge of earlier days. Sons of Soul, their third album, offers sly, respectful reminisces of the Isley Brothers and, yes, Sly Stone while asserting the guys’ own vision in its wittiest, most original form yet. The jumping “If I Had No Loot” updates one of the oldest blues complaints in the book, while the lush “Anniversary” acknowledges the most romantic moments of the year without letting reality out of its sights (“Tell your supervisor you’re leavin’ early today”). And moves both internationalist (“Dance Hall”) and just plain oddball (“Tonyies! in the Wrong Key,” a wry nod to Stone’s “Family Affair”) do their parts to make this a great R&B platter for any age.
