Most bands aspire to a large fan base that will eventually turn out in headliner-defining numbers, making its opening slot status a relic of leaner, hungrier times. The Canadian Indie/Folk/Pop twins of Tegan and Sara are certainly eager to attract more fans but they have absolutely no interest in abandoning their role as an opening act. They open for Paramore Thursday at PNC Pavilion.  

Get ready for a blazing show at PNC Pavilion: The Donnas in live mode are like a Russian porn star, Rockyer Cockov. For evidence, check out the group's latest CD, the ironically-titled 'Greatest Hits Vol. 16,' which offers up freshly recorded and live versions of old songs, a few B-side rarities and some new material. Fellas, hold on tight. Ladies, keep track of your wigs and keys. It's going to be a Donnas kind of night.  

Tool's viscerally shredding set is designed to elicit gyrational sweat even without the unrelenting, cloudless sun. The mayhem on stage is unstoppable — Tool ratchets up the volume and dark energy with almost psychopathic intent. Metaphorically, this is exactly how every Tool show has felt as the band agitates, cooks, refreshes, repeats. Thus may it ever be.   

It can be hard for a band to retain its indie identity when big labels start throwing money around, but Rise Against has never risen to that bait even when it signed to one of the biggest labels in the industry.  

Although most of its members hail from elsewhere, Ohio can claim a little local pride when the subject of O.A.R. arises.
