jcknbl pointed out some good Sarah records stuff (Heavenly, Field Mice, and so on), and I'll add to that.? Definitely listen to some Heavenly, though, they are fantastic.? He also mentioned Talulah Gosh, which was an earlier band containing a lot of the people from Heavenly, also centered around the singer Amelia Fletcher.? Heavenly broke up when the drummer, Matt Fletcher, Amelia's brother, committed suicide.? After a while, they more-or-less reformed as Marine Research.? Sounds from the Gulf Stream by MR is probably one of my favorite records of all time.? After Marine Research broke up, Amelia Fletcher started a band called Tender Trap, which is still together.
Other Sarah bands worth listening to are: St. Christopher, Brighter and Blueboy (listed in ascending order of litheness).? The Orchids are another famous Sarah band, but I always thought they were a little boring.
For North American stuff, check out Cub!? Much more of a punk influence than something like the Field Mice (although they go well with Heavenly).? Along those lines, also check out Tiger Trap and Gaze.
Then there was Kindercore records.? Kindercore isn't around anymore because its founder were comically bad at running a business, but they managed to put out a lot of fantastic records from:? Masters of the Hemisphere, Dressy Bessy, Of Montreal, and so on.
For more recent stuff, I'd recommend the following:
The Lucksmiths
Math and Physics Club
The Snow Fairies
Colin Clary
Locas in Love
Paula Kelley
Bearsuit
Darren Hanlon
The Gazetteers
Okay I'll shut up now.
