Query: a sincere and beautiful record

There is no other artist in the public eye who has continued to be as ingenious and wonderfully surprising as Beck. He seems to feel no need to stick to one particular sound, but rather allows himself to explore musically. With Sea Change he has achieved one of his greatest successes. Beck doesn't pull any punches with this album, but seems to be wearing his heart on his sleeve, so to speak and it is truly touching. He is much less guarded than on past albums. I think some fans of Beck's biggest hits may be a bit alienated by it, but for his dedicated fans and perhaps for a whole new audience, this record is a gem.
