Got this today from BEGN direct into my inbox:
We’re happy to release the first exclusive MP3 from Sonic Youth’s Buy Early Get Now. This track is from the Battery Park live LP that comes with Buy Early Get Now. It’s a ripper and a shredder and is available below in 320k mp3 or lossless FLAC format. Thanks to River and River for recording it. Enjoy!
Great job, great marketing, great people behind, great music, great band, just great.
