Should you know Kent Lambert, a solo artist who has brandished his keytar like he invented the thing, you’d know Songs the Animals Taught Us (2005) by Roommate, and you’d know how that debut album got Kent signed to Plug Research around the same time as David Thomas Broughton, another bedroom prodigy able to re-limn the walls of his bedroom. If you’ve been unaware of Kent Lambert, it might be safe to be reassured that his sophomore LP, scheduled for release in the fall, is an expansion—all signs point to maturity—because his band has grown from one and his voice has loosened, has a nascent breath. The evidence, the disarmingly great New Steam EP to be released electronically at the end of the month, is disarming because of its breadth, an exploration of a comfortably claustrophobic sound that, while still relatively tiny, creates an amalgam any solid EP should be: a whetting for the eardrums so that future noise involves a healthier snap.
