If you want to measure how well John O’Callaghan is doing right now, just take a look at his schedule, which features dates in Argentina and the Netherlands (as part of Armin van Buuren’s A State of Trance show), along with gigs in the UK, Slovakia, Canada and the US. Such globetrotting has helped O’Callaghan make his way onto the trance A-list (and the Top 20 of that ubiquitous DJ Magazine Top 100 poll), while his productions have ensured a big industry-wide buzz for the Navanman.

Tonight O’Callaghan launches Unfold, his third album, which showcases his patented sound of thumping energy and lush, slick, melodic appeal, as seen on boom tunes Find Yourself and Big Sky.

Aside from a three-hour set from O’Callaghan, tonight also features newcomers Aaron Cullen and Maria Healy.
