Here are some bands from Leeds:
Birds of Delay - Noise. Good noise. East coast US tour soon I believe. Former Selah, current Woman and of course both are members of Birds of Prey.
Tigers - Ex/current members of Eiger, Canvas, Humanfly, Cowtown, Brown Owl, The Dragon Rapide, Double Six Flight Team, Action Everybody... basically, they've been about, know their stuff and want to sex you up.
Humanfly - Sadly, these tracks only showcase the previous, more hardcore 'fly. Not that this wasn't awesome but in the past year they've cut down on the vocals and are kicking ass in the big, sort of epic metal vein. Basically, the kind of band the likes of Pelican wish they were. These guys have been/are in Canvas, Tigers, Beecher, J*R, Birds of Prey, Das Double Muslin Machine and Last Good Sleep.
Red Stars Parade - Huge, crushing grooves are the staple of Red Stars Parade. Isis comparisons have been hurled around about them before but they're way off the mark, presumably made just because they both play long heavy songs (although Red Stars are a fair bit weightier than Isis). 'Disko' was easily one of the best UK albums of last year.
Duck Stab - Yet another Leeds band with a daft list of ex/current members. Driven Down, The Devils, Unicorn Love, Charlie Don't Surf, We Are Corpses, Broken Access, No Excuse, Dungeon Nun, Holy Crap! My Face!, Jupiter Lander, Motley Crudos... We're an incestuous city, hence our vast quantity of bands. Pissed-up fast and dirty hardcore.
Like A Kind of Matador - Eerily beautiful doom, courtesy of McWatt, Trees, Tigers, Birds of Prey, Rauschen, Red Right Hand people. There should be an album out on Tumult at some point.
Benjamin Wetherill - Last time I saw this man play he did two George Formby covers. A superb folk singer with a very distinctive voice.
D-Rail - Proof that having an absolutely godawful name doesn't stop you being a good band. These guys have been around for years but have only just gotten around to a debut album just out on Calculated Risk (also home to Humanfly). Metalcore the way it ought to sound, but most bands in the genre are too busy dressing up like tits to get the music right.
And that's just the tip of the iceberg really. Leeds is shite for a lot of things, but music is the one area we excel in.
