I'll Be Your Mirror, Alexandra Palace, London N22

All Tomorrow's Parties' spring seaside festivals have stalled, but their hearty alterna-spirit parties on in this London spin-off, a three-day event thin on the chalet front but crackling with cult bands, rare reunions and evangelists of noise.

After 2011's Portishead jamboree, 2012 finds curators Mogwai and ATP dishing the decibels with speed-metal sadists Slayer's headline slot on Friday; supports include stoner-metallers Sleep, a band noted for recording a 60-minute track called "Dopesmoker" – and yes, it sounds like you'd imagine. Mogwai tower over Saturday, aided by noise mavens covering all bases from scary (Umberto) to sludgy (Mudhoney), immense (Codeine) and emotive (Dirty Three); Bill Wells and Aidan Moffat offer droll respite.

Sunday's retro bill includes Archers of Loaf, nostalgic nippers Yuck and a lusty coup in the shape of reunited narco-noir soul-rockers the Afghan Whigs (above), wherein Greg Dulli takes a swaggering walk not by the seaside but, assuredly, on the wild side.
