I wish I could remember which MP3 blog pointed me to it, but Creative misuse and abuse of musical tools has a rather large and nicely curated selection of "Glitch Electronica". From the site's About page:
"I am interested in the 'wrong' use of musical technology in the production of music, and the semiotics of 'wrong' sounds. This project is meant to serve as a documentation of such sound production over time, and as a means to make available music that may have been written about more than it has been heard."
The artists represented range from John Cage and The Beatles to Grandmaster Flash. Very cool stuff.
Meanwhile, welcome back to newly resurrected music blog NewFrontEars. After falling silent in late January, NFE is back to fill you in on the latest news about "contemporary and C20th classical, jazz, Baroque, improv, the outer fringes of rock, electronica, global... and a little Early Music too".
