Wreathed in legend, the vast labyrinth tunnels of Heaven gave us institutions like Paul Oakenfold's Monday night phenomenon Spectrum back in the acid house explosion of 1988 and the Thursday night proto d&b riot of Rage in the early-'90s. Woefully under-utilised in the present day, it remains one of London's most intoxicating underground experiences when in full flow, as anyone who checked last year's Carl Cox gig or the Easter Bedrock would well testify.

Circo Loco are amongst those who have taken up the baton for the venue in recent months. A true temple of rave.
