On Tuesday night, Grammy(R) Award-winning band Train take to the stage with an awesome performance of "Drive By," their first single from their latest album, "California 37," accompanied by Louis Van Amstel and Cheryl Burke. Pop sensation Selena Gomez and her band, The Scene, will perform their hit single "Hit the Lights." The Latin themed performances continue with this week's "Macy's Stars of Dance" performance called "Carnaval," a celebration of Latin dances featuring acclaimed percussionist Sheila E. The performance is choreographed by the talented Liz Imperio, who has directed Gloria Estefan's last three world concert tours and choreographed for Madonna and Jennifer Lopez. Also, this week's bottom two couples will face off in a Dance Duel. The two couples will perform the same dance style, this week the Cha-Cha, to the same song at the same time. The dance floor will be split in half as the couples dance side by side.
