The shuffling, one-two beat that dominates Triple P pumps like a piston, with sparks flying after every stroke. It’s a fitting focus for the Piper production duo of Wajeed and Saadiq, both Detroit natives. Their debut has been hailed as an example of next-level soul, but this vital and varied album works best when it remixes the past. “Now or Never” sizzles with a combination of double-dutch handclaps and soulful singing. The sexy R&B song “Fever” starts out like an Usher joint, but soon the joyful singing perfectly channels early Michael Jackson. If only other producers followed the Pipers’ lead.
