I had a chance to check out some of the new exhibits at the Boston ICA last week. I have yet to go there and not find something that I really loved and this time what I really like most was Nick Cave's "sound suits". You can read about the exhibit here but I suggest taking a look if you have the chance. The detail on these things is just awesome.
Also on exhibit at the ICA is some work from William Kentridge which includes a mind blowing immersive room experience with wall to wall projection and sound and some really interesting stuff from Christina Ramberg, an artist with an interesting style who died very young.
