For a while back there, Nottingham’s kosmic jammers Six By Seven seemed keen to set the controls for the heart of the sun and drift off into some kind of ever-expanding post-rock ionosphere. But they pulled back towards epic guitar territory with The Way I Feel Today two years ago, and their snappily titled fourth album continues the same trajectory towards super-heavy shoegazing of the Spiritualized/Valentines school. Rich in grand lysergic drones, fuzz-pedal overload and drowsy thunder, 04 remains as ’60s-fixated as any number of second-stage festival regulars. But Chris Olley redeems these trad tendencies with mighty sunbursts such as “Ocean” and “There Is A Ghost”.
