READERS' PICK: Although pyrotechnics no longer seem to be the special effect of choice at rock concerts--even Ozzy is family-friendly now--extreme fiery entertainment always can be found in the performances of Flam Chen, under the direction of longtime Tucson artist Nadia Hagen. This troupe is burning up the charts with its flame-centric gigs in the Old Pueblo. Its tours have caused other copycat groups to combust in cities far afield, as well. Flam Chen even gets a four-star review from the Tucson Fire Department, a representative of which always approves the group's performances and safety measures. Tucson Weekly readers offer this company a flick-of-the-Bic salute.
