We Are Smug is the side project of former Savage Garden frontman turned electropop showman Darren Hayes and collaborator and fellow electronic musician Robert Conley. Hayes and Conley had been working on this project secretly for about two years before releasing it online for free on Hayes's birthday. There are no current plans to tour or sell this album, aside from the free download, but there are already official music videos. (Warning: last link potentially triggering.)
Fuck Yuo I Am a Robot are offering their album Compensator for the Accelerator for free download from their site. Infectious ass-shakin' Estonian electro-pop. Lyrics to track 2 NSFW, likewise sleeve art jpgs if you opt for the .zip download. You can sample one of the tracks, Hydraulic, on YouTube if you don't know them and would like to check them out first, though personally I can't get enough of Zukunft (direct mp3 link).
WaxDJ.com - an excellent source for free downloads and streams of original electronic music mixes of all sorts, from seasoned pros to beginning bedroom amatuers, all told numbering in the hundreds or thousands. My current brand new favorite is the very diverse and well-versed Detriot/Chicago techno stylings of DJ Rubsilent. Recomended mix: Future Funk 23: (Direct MP3 link) (Streaming mp3 link) But don't let me divert you - search for your favorite local DJ or browse for new ones.
