The title of ATP's usually eclectic gathering at London's Alexandra Palace normally points towards the artier end of indie, pop and rock - it is named after one of the lightest and prettiest of Velvet Underground songs, as performed by Nico (and the flip-side to their "All Tomorrow's Parties" 7").

So when the line-up for the 2012 installment was announced, chins dropped, eyes rolled and Googles were Googled until we really were convinced that the organizers hadn't been pole-axed by West Country scrumpy the night before.

So instead of previous ATP-type artists like The Breeders, Teenage Fanclub, last year's Animal Collective et al, you have the gentle ear-hammerings of the marvelously noisy thrash-warriors, Slayer performing their exquisite and legendary splatter-platter, "Reign In Blood" in its entirety on the opening Friday (25th May), with support provided by the equally fearsome doom-metal outfit Sleep and grunge-cum-sludge band, The Melvins. A nice peaceful start, then - and that's only day one!

Saturday 26th May will feature post-rock Scots Mogwai, who will also curate the rest of the day's choices, which have so far been confirmed as grunge legends Mudhoney and the reformed slow-core band Codeine in their first public appearance since 1994. The final day on Sunday will see another respected and recently reformed band, The Afghan Whigs joined by Yuck.

More names will be announced in due course and we will have tickets from 10am on Friday. Prices start at £39 for Friday, £59 for either the Saturday or Sunday or £130 for weekend tickets, a saving of £27. If you are quick enough on Friday, you may just get your hands on Early Bird weekenders priced at £120.

Update: Guided By Voices have split

The original line-up for the 2012 edition of 'I'll Be Your Mirror' was to have included the recently-reformed Guided By Voices head-lining the Sunday night, but that will no longer be the case after they have split (again!). Taking their place are another recently-reformed band, The Afghan Whigs.
