8 Valentine's Day performances: Classy, sexy, funny

The star soprano headlines Arizona Opera's "Big Date Night" concert, and really, what music is more swoon-worthy than a soaring aria? This is a gala fundraiser, with cocktails, dinner and dancing, so the class factor will be high, as will the ticket price. Also performing are soprano Karen Slack and mezzo Daniela Mack, both of whom will be onstage in the opera's recently announced 2015-16 season (in "Falstaff" and "Carmen" respectively).
