Very little is known about the deeply anonymous Anstam, other than they have released only three singles of high-voltage industrial dubstep in three years. Emerging from somewhere deep within Berlin’s Hardwax camp, Anstam is apparently a pair of brothers who value quality control more than regular output. Those who have heard the singles – 2007’s “Aeto” and “Brom”; 2009’s “Cree” – liken the duo to the harder edges of the Skam and Rephlex catalogues. But there’s an undeniable rhythmic pulse underlying the music that speaks to dark, claustrophobic clubs. Anstam have also been taken under the wing of Modeselektor, who bring the duo over to North America for a debut performance at MUTEK under the banner of their Modeselektion night.
