Went to an interesting concert in December with wife, daughter andson-in-law to hear the Transiberian Orchestra. They were an absolute hoot and very good, but are hard to describe. A rock band, with orchestral components that include violins. Very heavy bass throughout. 4 male, 3 female singers. They did Christmas songs/carols in the concert. They also did an opera piece. Did I mention really heavy bass? Their next CD is all Beethoven.

I saw the Jack Johnson references on this thread and went to Amazon to check him out. They allow you to play 4-5 sample tracks from a given CD. I ended up ordering 2 of his CDs.

I recommend checking the Transiberian Orchestra samples. Very unique stuff and very good/entertaining.
