The title’s allusion to the form of employment in which a worker is paid a fixed “piece rate” for each unit produced seems a little churlish: While Pearson’s discography might imply that he’s churned the remixes out at a great pace, this 21-track retrospective also reminds that there’s enough quality in there to suggest that his acceptance of commissions is about more than just free-market economics. Compiling reworks of the likes of Closer Musik, Cortney Tidwell, Depeche Mode, and Goldfrapp (twice), Piece Work strikingly highlights Pearson’s faithfulness to the original “song,” as if his intent is to reframe the work of others rather than totally re-imagine it.
