You might remember Nicole Parker from her MADtv days of impersonating Britney Spears with hilarious lyrics like “Went to rehab, left too soon, made my hair look like the moon,” but Broadway-goers know her best as Elphaba, the evil melting green witch from Wicked. This week, the Santa Rosa Symphony teams up with Parker and fellow Wicked star Emily Rozek (Glinda, pictured) for Pop Wicked Divas, a concert of not only songs from Wicked but from Chicago, Phantom of the Opera, My Fair Lady and others, on Sunday, Feb. 17, at the Wells Fargo Center. 50 Mark West Springs Road, Santa Rosa. 3pm. $32—$75. 707.546.3600.
