Katy Perry is one of the biggest stories in pop music this year, but John Ross has done enough writing about her to account for the both of us, so I'll let his expertly written preview of Perry's appearance tonight speak for me. The ubiquitous voice behind such hits as "I Kissed a Girl" and "Ur So Gay" will headline the first night of WNCI's Jingle Ball at LC Pavilion, 405 Neil Ave. Your $30 also gets you Natasha Bedingfield, Thriving Ivory and Lesley Roy, plus host Nick Lachey. Doors open at 7 p.m.

And for those of you who like to be thwacked in the face by guitars rather than booty beats, Priestess will rock Ravari Room, 2657 N. High St. Cleveland's The Suede Brothers and our very own Vespin will also appear. 9 p.m. doors, $10 cover.
