More ambient goodness from Good Weather For An Airstrike, a UK project that was originally intended to create relaxing sounds to combat tinnitus and aid in falling asleep. Their sound is definitely relaxing, and inspired by such artists as Brian Eno and Godspeed You! Black Emperor. Overall this is definitely worth checking out.
Andrew Othling, aka Lowercase Noises, offers a superb album of ambient guitar music. Clocking in at almost two hours, the music barely moves but is somehow filled with motion, giving the sense of floating along on a galactic river full of light while watching the universe move from past to present to future. This is a sort of ambient postrock, as it is guitar driven with heavy use of effect pedals. Andrew posts much of his work on youtube, along with instructional videos of how to achieve his effects, He also offers three of his other albums (which I have not listened to yet, but have on my short list) on his website. You can also visit his facebook page and let him know his work is appreciated.
