Probably not anyone's favourite venue, but the local city council need to justify its existance after spending millions on it a few years back, so all the outdoor gigs are ending up here now. To its benefit, there are sea-views, nice open spaces, no neighbours to bother (and the city council HATE to bother neighbours...); on the down-side: all the stages interfere with the sound quality of the other, and it's not exactly the most centrally located venue in town. Still, this is Barcelona in the 21st century, and Forum is the venue of the 21st century.
