The wondrous Last.fm have partnered up with HP for a series of live music events and artist interviews called Power Of Sound to celebrate the new HP Beats audio technology.

The partnership kicked off with a secret pop-up acoustic session - hosted by the Black Cab Sessions -on June 16th in Soho Square, with a live performance from Sheffield duo, Slow Club, who performed tracks from their forthcoming album Paradise, which will be released in September.

More pop-up sessions are planned in London throughout July and August, all to be hosted by Black Cab Sessions in association with Last.fm, with the next one due to take place on July 14th in a secret central London location, with an as yet unannounced act.
