If you need to book flights, you need to make a note of the date of The Boiler 8th annversary event, which is over the 8th and 9th July 2011 in Barcelona.
Two nights, two live bands and two allnighters. The bands are The Excellos (Friday) and Ella and the Obsidians (Saturday), both playing from 11pm until midnight. After that until 5am, there's the allnighter with the Boiler residents joined by Chris Dale, Johnny Alpha, Bill Kealy and the wonderfully-named Tip Top Daddy for some soul and R&B dancefloor sounds.
It takes place at the Sala Jazzroom, Vallmajor 33 (Placa Adria), with admission 12 Euros for each night. Get in touch via the website for more details, accommodation help etc.
