Indie dudes and metalheads will break bread – and bang heads – this May in London, where Slayer will perform as part of the second U.K. staging of the I'll Be Your Mirror festival, an offshoot of the acclaimed All Tomorrow's Parties series.

As an added bonus, Slayer will celebrate the 25th anniversary of 'Reign in Blood' by performing that classic album from top to bottom, organizers announced.

Joining the seminal thrash act on the first – and certainly hardest-rocking – of the event's three days are doom-metal purveyors Sleep and Seattle sludge pioneers the Melvins.

The festival, co-curated by the Scottish post-rock band Mogwai, runs May 25-27 at Alexandra Palace, a venue that has previously hosted the likes of Led Zeppelin, Nick Cave and Pink Floyd.
