Is there any contemporary band that hasn’t been influenced by dub? Ex-Fink signer/songwriter/producer Finn Greenall’s new outfit, Sideshow, certainly has. Not that it’s a bad thing; endlessly reverberating layers of bass waves and spacey textures can connect a lot of musical ideas. There are straight-up dub tracks (“Sequential Dub,” “Youth of Today,” “Admit One”) on Admit One, but also interesting diversions into New Wave/indie (“Television,” “French Model in Dub,” “Bottletop Dub”) and broken-beat dancehall (“If Alone,” featuring Paul St. Hilaire). Think of this as an indie rock album that substitutes a Quadraverb unit for a jangly guitar and a spliff for a pint, and you just about catch Sideshow’s drift.
