Just got back from seeing them here in Buenos Aires and found this thread on Google. I saw Rain earlier this year in St. Louis...both excellent. I think Rain was better, but I only say that because The Beats struggle a little with lyrics, not being native English speakers. The Beats also stuck to the hits (for the most part...they delved into Love You To, The Night Before, You're Going to Lose That Girl), whereas I seem to remember Rain playing a bunch of songs you wouldn't consider to be "hits."
