My playlist this evening (albums, not tracks):
Choir Of Robots - Clementine Star [2012]
YMCRT (Righteous Fist/Effi-G) - Thunder & Frightening/Hit The Stage [2012]
Duane Eddy - Have 'Twangy' Guitar, Will Travel [1958]
Duane Eddy - Especially For You [1959]

Battles - Gloss Drop [2011]
King Crimson - In The Court Of The Crimson King [1969]
The first two (well... three actually, but that's different) are friends of mine, and both of them are free, so you should definitely check them out. The links on the titles are to their respective Bandcamp pages.
