A mix of local unsigned groups and touring bands from the States, Australia and Japan pass through this 300-seater. Punk, rock, ska and 'mestizaje' tastes are catered for, with regular rock competitions, the prize being the chance to professionally record an album. An excellent sound system makes it worth the trip out to the 'burbs. Among the audience you’ll find plenty of people wearing studded leather jackets, jeans and cowboy boots. And house band Gruta 77 is also very active. Until 2008 the concert hall published a rock magazine, and it still has a number of rehearsal rooms for Madrid-based bands.
