The genre formerly known as post-rock has had a long, convoluted, and troubled history. It was originally used in print by the rock critic Simon Reynolds to describe bands like Talk Talk and Bark Psychosis, who were bringing in elements of less whitebread music - disco, African rhythms, jazz, krautrock, and Jamaican dub -- and extending their structures to more widescreen classical formats, and blending them with the primal fury of rock 'n roll. Post-rock may have also been the last and greatest victim of co-option and conformity (or can at least share that honor with dubstep), before finally succumbing to postmodern dissolution for good. What became of post-rock? Oh-so-serious dudes in black clothes with long band names, mindlessly aping Mogwai and Explosions In The Sky, turned what could have been the most promising mixture of head and heart, guts and chops into a marketing cliché. Thankfully, the German instrumental duo Sankt Otten rewind the clock with Engantz Depression, and make us reassess the possibilities of blending rock instruments with electronic music for a compelling hybrid that takes post-rock back to its roots, to begin again.
