Away from the jazz faction, post-rock’s stately drift towards classical music continues apace with the release of the Threnody Ensemble’s debut album. Like Rachel’s, their most obvious contemporaries, the San Diego collective make the ideal soundtrack to those poignant moments in the conservatoire. Actually, Timbre Hollow is less precious than that. A lot of artful acoustic guitar, cello and clarinet, for sure. But there’s unexpected wit and catholicism, notably when a salsa groove gatecrashes the tranquillity of “Tha Roman (Formerly Valerie White) Part 2”. Engaging.
