I should really read
Largehearted Boy more often; he has recently posted a number of links to MP3s online, including a trove of
tracks from Slowdive EPs (at 128kbps, though). These are really good; if you haven't heard them, go and download.
Also via LHB, Luis Buñuel's Un Chien Andalou, in a MPEG file. If you were wondering what exactly The Pixies' Debaser was about, that's it.
