It’s hard to keep up with the output of Cooper B. Handy (aka Lucy), who’s been dropping music at an insane clip for more than a decade. The fact that he rarely misses makes this release rate all the more frustrating for the completionists among his organic, devoted fanbase. The Hadley, Massachusetts pop visionary has produced the lion’s share of his records to date, developing a signature style that stretches the limits of GarageBand’s potential as a digital audio workstation. Increasingly, though, he’s been letting others take, or at least share, the reins. His new, unheralded album 100% Prod. I.V. is, as its title implies, an example of the former tactic. “Rather mysterious Minnesota producer I.V,” as she’s referred to in the project’s bio, shares Lucy’s penchant for clearly synthetic yet disarmingly earnest sounds, perhaps pushing the envelope even further in that regard than her new collaborator has. Lucy’s lyrics, alternately Seussical (“What’s done is done, what’s said is said / So I wake up in the morning and I make my bed”) and [Harry] Crewsian (“I need a blood transfusion and an oil change”), sound both at home and alien over quantized guitarpeggios and other preset plugins tweaked to gummy nirvana. Standouts include the nomadic ballad “Better,” the glitchy Masshole anthem “What She Said,” the harmonica-dosed nostalgia pill “Tank,” the soaring ballad “Faith Hill,” and “Substance,” in which Lucy tunelessly interpolates the Christmas carol “God Bless Ye Merry Gentlemen” over I.V.’s chirping trap beat to revelatory effect. — Raphael Helfand
