The sister event to the long established All Tomorrow's Parties festival, I'll Be Your Mirror returns to London's famous Alexandra Palace from Friday 25th until Sunday 27th May. Following on from last year's successful event curated by Portishead and ATP, this time around Mogwai have joined with ATP to assemble the music line-up, with a cinema programme curated by Mogwai, London's Prince Charles Cinema, Louis Theroux and ATP. The headliners on each of the three days are festival exclusives – these will be the only UK shows of 2012 for Slayer (Friday) and the specially reformed Afghan Whigs (Sunday), whilst Saturday night will see Mogwai's only English show of 2012.

Friday's line-up is on the heavier end of the musical spectrum with regular ATP favourites such as Melvins and Sleep as well as newer acts like A Storm of Light and Yob. Two undoubted highlights will be the appearance of the dark ambient/ black metal duo Wolves in the Throne Room, and metal legends Slayer who are billed to play their classic 1980's album Reign in Blood in full in the Great Hall.

Saturday and Sunday offer more varied bills, although interestingly neither day uses the Great Hall and all of the acts are split between the West Hall and the smaller Panorama Room. There are around 26 acts spread over the two days and they range from up and coming acts like Balam Acab, Forest Swords and Demdike Stare, to rarely-seen reformed legends such as the Make-Up, Afghan Whigs, Chavez and the long lost inventors of sadcore, Codeine. There is also Bill Wells and Aidan Moffat, synth-punk from the Soft Moon, an exploration of the Can re-issues with Irwin Schmidt from the band,and a festival closing set worth hanging around for from El-P.

Add to that the return of festival regulars Dirty Three and Mudhoney, plus that Saturday night headline set from Mogwai, and the weekend is looking very impressive indeed.

Although the prospect of attending an ATP festival where you don't actually stay overnight initially seems a bit strange, there are plenty of familiar events for ATP regulars, such as Lord Sinclair's Rock n Roll Bingo and Quiz, the Mixtape swap and the Book club.

Some day tickets are still available from here.
