My Bloody Valentine

My Bloody Valentine, Roundhouse, London

Lesser talents be warned – My Bloody Valentine are back, hunting a legacy frittered away by their own procrastination and lazier groups that took on their mantle. The group re-form here after a 16-year absence, during which band leader Kevin Shields scrapped an album and went into isolation. Fans would be forgiven for expecting to find the venue still being built. This is the band, after all, that took three years to record their 1991 masterpiece Loveless. Last week, Sony BMG was due to re-release the group's two albums, a project delayed since Shields is late with the sleeve notes to explain his remastering process.

“It means a lot you came out tonight. We don’t expect it, a small band from Glasgow. We’ve been down a few times and you didn’t come then,” The Twilight Sad’s singer James Graham says wryly. Perhaps it’s the former Arab Strap Malcolm Middleton’s recent endorsements of the band that have lured the sizeable crowd.

Album: Speck Mountain, Summer Above (Peace Frog)

This debut release from Chicago indie trio Speck Mountain will gladden the hearts of all those pining for the drowsy haze of Mazzy Star, the dense guitar clangour of My Bloody Valentine, and the churning riffs of The Velvet Underground.
