Where to start... Okay, I don't want to throw too many in here but "favorite" for me depends on the mood I'm in so.. Let's just do mood favorites. Now no moods will be listed just the bands. Confusing, I know. Here they are: LCD Soundsystem, Liars, Smashing Pumpkins, Bjork, The Misfits, Dead Kennedys, Black Flag, The Knife, Fever Ray, Otto Von Schirach, Venetian Snares, Aphex Twin, Metronomy, Fugazi, IDLES, Black Midi, Zeal and Ardor, Behemoth, Arch Enemy (Angela Gossow years!), Slayer, Ministry, Skinny Puppy, Author and Punisher, Melvins, David Bowie, Led Zeppelin, The Grateful Dead, and let's round it out with the Butthole Surfers. I know, still a ton of 'em. Now they were kinda grouped by mood but, not fully. Sorry! Great question though! <3
