Thanks for your suggestions...
Thanks to everyone who's suggested under-the-radar acts worth checking out at SxSW. Safest way to send 'em is via email at introducing.6music@bbc.co.uk - meanwhile here's where you can hear the recommendations people have made so far - see what you think:
CADENCE WEAPON - In Search of the Youth Crew
(Fanstastic indie hip-hop from the frozen tundra of Canada) - can't argue with that. oldskool rhyming over fresh contemporary beats.
THE AKRON FAMILY - Franny You're Human
Weird acoustic oddball noodling from Pennsylvania.
BE YOUR OWN PET
A kind of collision between the B-52s and the Yeah Yeah Yeahs who've been lighting up 6 Music's radar since 2004 with 4 minor UK hits. Huge fun, if you don't know them.
SUNBURNED HAND OF THE MAN - Burnie Is Coming
good, but a bit selfconsciously odd & lo-fi
THE MAE SHI - Run To Your Grave
great tune, really fresh: Devo-ish foursquare beats w. farfisa organ.
BLACK MOUNTAIN - Stormy High
(huge slightly proggy riff tastic but with a sense of beauty)
DÄLEK - Eyes To Form Shadows
(Dark Hip-hop poetic and harsh) over appealingly industrial-grade noise.
DEER TICK - Song Of Samuel
(Singer songwriter, americana) 21 yr old John McCauley. Harsh vocal stylist over sweet guitar backing - good contrast
HERMAN DUNE - I Wish I Could See You Soon
(Catchy blues/folk, sense of fun and self deprecation). Is there such a genre as anti-country? This would be it.
NADJA - Fiend
(Ghostly drones and very dark) Hoarse metal riffing
PISSED JEANS - Ashamed Of My Cum
(Proper angry scuzzy heavy punk). Great MySpace profile too - no friends, no pictures, no info, no comments. And 29,000 plays
SOILED MATRESS & THE SPRINGS - Someone's drinking water
Archly retro sax'n'keyboard instrumentals from NYC - touring UK in May
And no, I don't particularly like or wish to promote Mr Murdoch's MySpace.
But on the other hand MySpace pages are a uniquely useful leveller when comparing artists, because these days everybody's got one.
