Bardo Pond @ Mono

Tonight's trio of consciousness-expanders begins with Alexander Tucker, who builds walls of textured drone that belie his lone, seated figure. With bowed guitar, acoustic arpeggios and wordless vocals, interspersed with occasional bursts of heavy noise, he masterfully commences a night of psychedelia.

Live, Jackie O Motherfucker are a long way from the accessibility of last year's Flags Of The Sacred Harp. They play long, improvised organic jams, formed from a multitude of bowings, scrapings, drifting ghostly voices and shamanistic chanting. Over the course of an hour, their shuddering drones slowly rise and fall, coalescing every so often into half-songs and melodies.

Bardo Pond's similarly trance-inducing sounds are of a wholly different kind. The air is thick with their heavy riffs, the sound so dense that it seems to tune the whole venue into their monolithic bass-heavy grooves. With the unstoppable juggernaut of Clint Takeda's bass and Jason Kourkounis' drums against the deep fuzz of the Gibbons brothers' dual guitars, all overlaid with the barely-heard whispers of Isobel Sollenberger's flute and vocals, Glasgow is treated to a wonderful dose of the finest psychedelic rock around.
