Anna Meredith may have composed for the BBC Scottish Symphony Orchestra, but she’s also written a piece for an MRI scanner. Echoing that breadth of approaches, her debut album blends classical leanings (clarinet, tuba, cello) with bubbling electronics and Dirty Projectors-esque avant-pop. The Scottish-born, London-based composer stokes pinging, bass-buffeted melodies on opener “Nautilus”, while “Taken” moves to distorted guitar and a quasi-rock chorus. Whether turning to epic synth odysseys (“The Vapours”) or sugary electro-pop (“Something Helpful”), Varmints accumulates more giddy ideas with every passing minute.
