I’ve mentioned this before, but it’s worth mentioning again as Biosphere is performing in London tomorrow night (Thursday) at St John Sessions. Biosphere!

The ambient mastery of Norway’s Geir Jenssen in full effect hosted in the beautiful St John at Hackney venue. What’s not to love.

From his early days as an unlikely player in the nascent bleep-house movement, Biosphere’s more than comfortably settled into a monolithic groove as one of the greatest ambient artists of all time. Sampling everything from Twin Peaks to abandoned silos, he’s a master of ‘arctic ambient’; sound that invokes an environment from the icy tundra (on the landmark Substrata) to Japanese nuclear silos (2011’s N-Plants) to St John’s Church in Hackney. Biosphere’s live sets are notorious; a towering testimonial to his enduring appeal – taking in the full breadth of his work from field recordings to plucked strings, ambient blips to jazz-inflected rhythms.

As if that wasn’t quite enough, techno heavyweight Perc will be performing a rare ambient set (which was premièred at Germany’s Krake Festival in August) alongside EQLS  – an experimental collaborative project between Milo Fitzpatrick (Portico Quartet) and Nick Siddall (Morviscous, Talk In Colour).

More details (and tickets) are available on the RA event page.
