CHEECH & CHONG LIGHT UP AMERICA: The hilarious duo that ruled '70s cable television return with more extremely deep observations on life (and hopefully one or two classic routines in the supremely mellowed-out mix). Saturday, December 6. Gibson Amphitheatre, 100 Universal City Plaza, Universal City
AIMEE MANN'S 3RD ANNUAL CHRISTMAS SHOW: Few people can make a traditional carol sound so modern and, well, emotional.

Saturday, December 6. $25 and up. The Wiltern, 3780 Wilshire Boulevard, Los Angeles. 213-380-5005
JOHN MAYER ON HIS OWN: With the singer-songwriter popping up on the tabs every third week or so, it is good for people to be reminded the man can craft a compelling tale in addition to rocking the guitar. Brit pop sensation Adele opens. Saturday, December 6, 8PM. $69.50. Nokia Theatre, 777 Chick Hearn Court, Los Angeles.
