HP and Last.fm recently announced a partnership, celebrating the Beats audio technology that comes with HP Premium PC, laptop and tablet devices through a series of live pop-up sessions and artist interviews, curated by Last.fm.

Following previous sessions with The Boxer Rebellion and Slow Club, the final pop-up session took place last month when Ghostpoet (aka Obaro Ejimiwe), hit up The Big Chill Bar in London's Brick Lane, to perform tracks from his Barclaycard Mercury Music Prize nominated album, Peanut Butter Blues & Melancholy Jam.

Here's a quick recap of the session (including an interview):
