Glad I found this topic, I was planning to start one about experimental, post-punk and alternative music myself!
My musical path changed drastically when I stumbled across the John Peel show in the early 80's, which got me big into acts like Killing Joke, Bauhaus, Joy Division, The Fall, The Cure, Cabaret Voltaire, Sisters Of Mercy and a seemingly endless list of other artists... got very much into almost everything on 4AD at one point, but the music turned a bit too 'soft' for with acts like Lush and The Pale Saints appearing on the label... Dead Can Dance were probably my favourite band on 4AD, with Cocteau Twins, Dif Juz, Modern English, Xmal Deuchland, Wolfgang Press, Clan of Xymox being other favourites... Other artists that really floated my boat, and still do, are Big Black, Death In June, Swans, Current 93, Radiohead, Portishead... too many to list really... my taste drifted towards drone, experimental, noise and general weird shit, with artists like Beequeen, Alio Die, Muslimgauze, Band of Pain, Novy Svet, Ait!, Mushroom's Patience, Andrew Liles, Bardoseneticcube, Chaos as Shelter, Agnivolok, The Hafler Trio, Nurse With Wound, Godspeed you! Black Emperor, Amir Baghiri, Tor Lundwall, Exit in Grey, Contagious Orgasm and too many others to list!
Anyone else here into this stuff??
