Acid

Acid is the sound of one machine : the Roland TB-303 and its squelching, resonant bassline, the noise that lit the fuse for the whole rave era. On calrave it threads through techno, trance and the harder styles rather than standing alone, and it has real champions. Thunder in Paris, Le Coven in Lille and Son Libre in Bordeaux all weave the 303 into their nights, and Madrid's wide-ranging Mondo Disko makes room for it too. You'll also catch it on big festival stages, from Sónar in Barcelona to the Monegros desert rave in Aragón and Fort Décibel near Bordeaux.

Warm, hypnotic, instantly recognisable : acid is as much a texture as a genre. Below you'll find every upcoming acid date we track in France and Spain : club nights, festivals and open airs, hand-checked and updated as new lineups land.
