Boston Common Holiday Tree Lighting
Boston will continue its transformation into a winter wonderland with the Boston Common tree lighting just before 8 p.m. on Thursday, when the tree from Nova Scotia will be illuminated, quickly followed by a pyrotechnic display. The festivities will kick off around 6 p.m., and WCVB will broadcast live from the Common starting at 7 p.m., with appearances by multi-platinum singer-songwriter and Lexington native Matt Nathanson, award-winning Nova Scotian alt-pop stars Neon Dreams, Nova Scotian R&B singer-songwriter Zamani, and others. (Thursday, Dec. 5 from 6 to 8 p.m.; Boston Common, Boston; free; all ages)
Hear your favorite holiday classics, sing along with the symphony, and even catch a glimpse of Santa Claus during the Boston Pops’ holiday season, which kicked off on Wednesday with conductor Keith Lockhart celebrating his 25th year leading the annual celebration. This year’s concert centers around “The Polar Express,” with images from the 1985 book projected on the screen as the orchestra plays tunes from the 2005 film. (Now through Tuesday, Dec. 24 at various times; Symphony Hall, Boston; $25-$162; all ages)
If “The Nutcracker” is too traditional or too expensive for your tastes, its raunchier, more affordable sibling “The Slutcracker” will bow at the Somerville Theatre starting Dec. 6. The burlesque parody created by Vanessa White in 2008 is not a family-friendly affair, but for those who prefer their ballet with a heavy dose of the risqué, “The Slutcracker” is just the ticket. (Friday, Dec. 6 at 8 p.m. through Tuesday, Dec. 31; Somerville Theatre, Somerville; $30; 18+)
Cher still goes all out for her live shows at age 73, and her upcoming show at TD Garden this Sunday promises to be no different.

(Sunday, Dec. 8 at 7:30 p.m.; TD Garden, Boston; $47.95 and up; all ages)
