Within just 24 hours of its Aug. 7 release on the online music sharing platform Bandcamp, “Volume 2,” the sophomore effort of Boston-based prog-rockers Perhaps, became the site’s number one-selling experimental album. Along with bassist Jim Haney, guitarist Sean McDermott, and drummer Don Taylor, “Volume 2” also features the synth stylings of Cotton Casino, founding member of the Japanese psych ensemble Acid Mothers Temple.
Over the past year, Perhaps has earned a reputation for creating highly technical instrumental soundscapes that bend and blend musical genres. Perhaps’s debut, 2012’s “Volume 1,” set the prog-rock blogosphere abuzz; despite this categorization, the band describes its music as “stargaze.”
Composed of a single, 30-minute track, “Volume 2” marks the band’s departure from its earlier jazz-fusion sound to more psychedelic influences. The textured, electronic introduction features wild saxophone playing by Tom Weeks overlapped by hypnotic synthesizers, creating a far-away effect. Grumbling bass notes lead into complex rhythmic structures that alternate with space-rock stretches, punctuated midway through by unapologetic solos from each member. The album ends with a dramatic instrumental climax followed by fuzzy, electronic screeches — it sounds like an alien radio catching one of Earth’s stray frequencies.
Perhaps performs at the Wilbur Theatre with space-rock vanguards Hawkwind and fellow Bostonians Art Decade on Oct. 10.
