This was an early disc by the duo and it doesn't sound quite as good as the newer studio or live album. Both of the newer works are available in the states now, so unless you are major fan, this disc is safe to skip. It seems like some of the songs overlap with later work (under different song titles?). There is a bit of a stronger spanish/mexican flavor in some parts of this, which some people might find interesting.
I recently saw them in concert and had a great time. Well worth it if they come near you (US Summer 2007).
