The audience sits in hushed reverence while the click of an effects pedal is audible, almost as if it's the sound of a dropped pin. Clearly this isn't any ordinary gig.
Winding up their joint UK tour, Clogs and the Books are both enjoying critical acclaim. What's most striking, though, is that despite the differences in their music, pairing these two acts together seems like a hugely inspired decision.
Clogs, a quartet led by arranger Padma Newsome, create a rich sonic tapestry, interweaving strands of guitar, viola and bassoon. Percussion is mostly kept to a minimum, although as on Canon, which evokes thoughts of Ry Cooder and early Tortoise, the melodies are oddly rhythmic too.
Their airy, cinematic chamber rock is most similar to Rachel's, and the sumptuous instrumentation displayed on their excellent new long-player, Lantern, is evident throughout their stirring performance.
The Books are an entirely different prospect, but no less engaging. A duo comprising of guitarist Nick Zammuto and cellist Paul de Jong, they conjure irresistible sound collages from field recordings and more conventional arrangements.
Largely drawing on material from their two most recent albums, The Lemon of Pink and Lost and Safe, repeating melody patterns slowly embed themselves in your brain, and it's difficult not to admire their shimmering, folk-indebted electronica.
On Smells Like Content, Zammuto's lyrics, projected on a screen behind him, which seem to be have been chosen purely for their rhythmic qualities, and it only adds to the impact of their stunning set.
While both acts are magnificent in their own right, perhaps the best moments are when they collaborate, with the bands joining each other at the end of their sets. It makes for an evening of beautiful music, suggesting that neither Clogs nor the Books will remain closely-guarded secrets for long.
