Polish festival Unsound marks its eleventh anniversary this year, hosting a number of electronic acts and audio-visual projects under 2013’s curatorial theme of “Interference”.

Added to the already weighty program, which includes Porter Ricks, Earth, RP Boo and King Midas Sound, are Modern Love label mates Andy Stott and Demdike Stare, who will be performing a unique commissioned piece called “Eutectic”, conceived with the “Interference” theme in mind.

Hessle Audio co-founder Pearson Sound will also join the list, along with the first European showcase of New-York/Berlin-based label White Material who will be presenting techno and house sets from Young Male, DJ Richard and Galcher Lustwerk. Jenny Hval and Forest Swords also make their debuts at the Polish festival, showcasing their experimentally ambient sounds. Closing the club music will be pioneering techno artist Regis, presenting “Necklace of Bites”, which he describes as "a twenty-year retrospective of Regis, re-sequenced and dissected for this special performance".

A one-off for the festival is The Mulholland Free Clinic, a 'supergroup' bringing together Magic Mountain High and Reagenz that will see Move D, Jonah Sharp and Juju & Jordash (read our recent interview with them here) playing a live improvisation, laptop-free.

Unsound also hosts a number of Polish acts including Krakow's Sinfonietta Cracovia who will perform a special version of multi-instrumentalist Oren Ambarchi’s "Knots", whose last LP we reviewed here, as well as Robert Piotrowicz who is teaming up with Yellow Swans’ Pete Swanson, who we interviewed late last year.

Another name that we're hugely excited about is Stara Rzeka, Polish artist Kuba Ziołek's one-man amalgam of black metal, neo-folk and electronica, whose album Cień Chmury Nad Ukrytym Polem was recently featured in our Editors' Picks.

More names are to be announced soon and the earlier line-up announcements can be found at Unsound's website. Tickets go on sale this Friday, June 21.
