The offshoot to the infamous All Tomorrow's Parties Festivals, ATP: I'll Be Your Mirror, is to return for a second year following the success of last years event held at Alexandra Palace.

The three day event will run from 25th-27th May, with Friday seeing Slayer perform Reign In Blood live in it's entirety during their headline set to celebrate it's 25th anniversary. Metal trailblazers Sleep will support, in their first UK visit since reforming for two amazing ATP festival shows in 2009, alongside Melvins, with more acts to be confirmed.

The first ever curators of the ATP Festivals, Mogwai, will return to headline the Saturday in their only scheduled live show in England in 2012, whilst they are also curating the day and have thus far chosen Mudhoney (their first shows since 1994 - and with their original line-up) and Codeine to play.

Sunday sees the reformed Guided By Voices at their first UK show since 2003, and Yuck are the only confirmed act on this day so far; but with ATP curating this day you know the full line-up will be quite something.

Friday-Sunday Weekend Tickets will cost £130 - a limited amount of Early Bird Tickets will be available priced at £120.

Friday Day Tickets are priced at £39. Saturday and Sunday Day Tickets are priced at £59.

Tickets are on sale via ATPFestival.com from Friday 11th November at 10am.
