With an opening year on the books, it looks like Happy Hour Concerts are here to stay. The Florida Orchestra figured last year it was time to create a user-friendly atmosphere geared to 9-to-5 commuters who could use the stress relief. Now the seasonís first Happy Hour Concert starts anew, this time with an additional series sponsor, Cigar City Brewing. That means free Cigar City beer will flow at this event built around relaxation. Bars are open throughout, and patrons are free to come and go from the concert. Stick around afterwards for a meet-and-greet with musicians. The hourlong concert will mix festive tunes in keeping with this yearís ongoing celebration of the orchestraís 50th anniversary, including Christmas themes and selections from The Nutcracker. Stuart Malina conducts. 6:30 p.m. Thursday (bar opens at 5:30 p.m.) at the David A. Straz Jr. Center for the Performing Arts, Ferguson Hall, 1010 N MacInnes Place, Tampa. $35. (727) 892-3337. floridaorchestra.org.
The Book of Mormonís producers have made lower-priced tickets possible for a few lucky fans. To win a $25 ticket (thatís less than half of the starting price for seats), itís safest to show up two and a half hours before curtain. One lottery entry per person, limit two tickets per winner. The show by the creators of South Park is back in the Tampa Bay area after several successful runs in recent years, a testament to the popularity of this quirky, irreverent hit. Through Sunday at Tampaís Straz Center. $63.75 and up. (813) 229-7827. strazcenter.org.
Improv actors get a lot of satisfaction cycling through various levels of training. They write sketches and perform cold, ready for whatever someone throws out. But nothing beats those special nights when they get to try out their chemistry in front of an audience. Thatís what happens the second and third Sundays of each month, when the American Stage Improv House Teams present an evening of off-the-cuff comedy. All teams are made up of American Stageís training program graduates and do long-form sets. Participants include the Wet Bandits and Possible Side Effects, plus an opening set from a local indie troupe. 7 p.m. Sunday at the Raymond James Theatre, 163 Third St. N. $10. (727)823-7529. americanstage.org.
Pianist and composer Sarah Cahill, who has toured the country playing with symphonies and in solo concerts and recorded more than 20 albums, swings through St. Petersburg and Sarasota.

The two concerts are not identical. The first, a solo piano performance, starts at 3 p.m. Sunday at the St. Petersburg Main Library, 3745 Ninth Ave. N, St. Petersburg, and is free. thenewmusicconflagration.org.
