4AD sampler streaming here and for free download.

This is a really interesting compilation, it's amazing given that British label 4AD went through the most of this decade almost unnoticed, pushing the wrong emerging bands (with the notable exception of Blonde Redhead) and getting mentioned only for the odd Pixies compilation.
If there's still some irritating stuff, like the kitch retro of Camera Obscura, the most of the bands (some Americans, some English) bring a refreshing sound and are worth investigating: Atlas Sound is the solo project of Deerhunter's Alex Cox, both play a unique take on psychedelic noise, Tune-Yards's fragmented mix of melody and rhythm sounds really original, M Ward's ethereal ballad seems inspired by Bowie's Low and Future Of The Left play an excellent revision of At The Drive In.
Best of the bunch are The Big Pink, which blend perfectly baggy and shoegazing, and St. Vincent which confirms Annie Clark as a genius as inventive as Bjork with an eclectic and emotional song.
The rest of the playlist is pretty average contemporary indie folk, or post folk, but discovering six interesting bands out of 12 is good enough.
