Off Festival Katowice 2010, which will be held August 5 to 8 in the Silesian metropolis Katowice, in Dolina Trzech Stawów, is an event where you can expect to hear all kinds of relevant, ambitious music. The following is a list of 10 more confirmed artists:

We are glad to confirm that one evening will belong to a favorite band of the late, great John Peel: the legendary London duo DIGITAL MYSTIKZ, a driving force behind the dubstep scene. Suffice it to say that Mala and Coki are also the brains behind the influential DMZ label and the eternally packed Brixton club by the same name. What will their fat and dirty bass lines sound like when transplanted from a London club to the calm, verdant Dolina Trzech Stawów? We can’t wait to find out.

The velvety voice of Swedish vocalist Victoria Bergsman is well known to all. You may have heard her on songs by The Concretes or Peter, Bjorn and John’s great hit, “Young Folks.” Bergsman comes to Katowice with her own project called TAKEN BY TREES, one that appeals to the heart as well as the ears with her ethereal, indie-folk songs. We like Taken By Trees because she shares our conviction that music should know no boundaries. She recorded her last album, “East of Eden,” in Pakistan with local musicians, while winning over demanding western crowds with her bold renditions of songs by The Animal Collective… and Guns ‘N’ Roses.

THESE ARE POWERS is a musical collective from New York and Chicago known for experimenting with rhythm and noisy guitar sounds. The band founded by ex-Liars bassist Pat Noecker may surprise you with its punk rock left jab, polyrhythmic labyrinths, and catchy, pop melodies. And who knows what else, if they top off their setlist with a jam. Says Noecker about his influences: “just walking down the sidewalk and seeing something interesting or hearing something interesting that someone says. Everything is an influence. It ranges from peaceful to very chaotic and intense, and all those things, I think, subconsciously come out in the music.” That about sums it up.

The Italian trio ZU plays extreme metal, but in a jazz ensemble: drums, bass, and baritone sax, with the occasional electronic gadget thrown in for good measure. Their unbelievably massive sound and the ease with which they combine these distant musical realms makes quite an impression live. Their greatest fan (and publisher) is Mike Patton. And John Zorn, who described ZU’s work as “a powerful and expressive music that totally blows away what most bands do these days”

Hard as it may be to believe, the Norwegian band SHINING is even more extreme. The title of their latest album says it all — “Blackjazz.” Interestingly, the band started off over a decade ago as an acoustic group, while their current material is a combination of free jazz, Scandinavian black metal, and King Crimson’s best years. Powerful stuff.

Los Angeles’ DUM DUM GIRLS are a quartet led by the humanly charming and inhumanly talented Dee Dee. She borrowed the name from an Iggy Pop song, while her energetic music also owes a bit to The Stooges and other punk classics, as well as pop girls bands from the 60s. No wonder Dum Dum Girls are one of the most important new bands on the Sub Pop roster, and NME describes them as “more than just another garage rock pastiche, these girls have real heart,” while Pitchfork adds: “[Dee Dee’s] voice is often deeply mysterious and feminine and other times coy and a little perilous.”

BEAR IN HEAVEN (USA) — Psychodelic, ambitious rock from Brooklyn. “This is music that’s bigger than your iPod — music you’ll want to feel all around you,” reads a raving Pitchfork review. Get a chance to experience it at Off Festival Katowice.

MIKROKOLEKTYW (PL) — Members of the legendary Robotobibok, trumpet player Artur Majewski and drummer Kuba Suchar, who perform live alongside a minimoog and sampler, are a watershed on the Polish stage. They’ve just published their debut album, following five years of excellent concerts. And they’re finally playing at our festival.
