These psychedelic rockers build up the sparse folk experiments of their 2012 debut, On an On, into lavish odysseys on their follow-up. Now with trippier violin filigrees, they sound even more like the offspring of groups like Soft Machine and Caravan – the similarly minded rock alchemists who populated their native Canterbury, England, in the late Sixties. On catchy standouts like “Autograph” and “Chariots,” the band settles into entrancing, sometimes repetitive grooves. Not even modfather Paul Weller, who guided the songwriting on “Hometown Blues,” could make these guys break free of their instant-vintage tunnel vision. Their maybe-namesake, Syd Barrett, would have approved.
