A non-comprehensive list of upcoming new releases that I'm looking forward to (and that you should be too!):
Aphex Twin- ???- March 12, Warp?
Falty DL- You Stand Uncertain, March 14, Planet Mu
FABRICLIVE 56: Ramadanman/Pearson Sound - March 21, Fabric
Moon Duo- Mazes- March 29, Sacred Bones
Bibio- Mind Bokeh- March 29, Warp
Prefuse 73- The Only She Chapters- April 25, Warp
Explosions in the Sky- Take Care, Take Care, Take Care- April 26, Temporary Residence Ltd.
Tyler the Creator- Goblin- April, XL
White Denim- D- May 24, Downtown
Shabazz Palaces- Black Up- May 31, Sub Pop
My Morning Jacket- Circuital, TBA, ATO
Of course, there are the ubiquitous rumours flying around as well: Burial, Portishead (Album 4), etc. So far, 2011 has been a good year for sounds, and I have a feeling it's only going to get better.
