The Old Rock House was glowing as Free Energy took the stage on Friday night. Really, truly glowing.

Free Energy is an exuberant Philadelphia-based rock band that plays the kind of pop-rock that sounds perfect in a stadium or a club.

Still melancholy over the loss of Davy Jones? Soothe yourself with a nice list of forgotten classics by the Monkee.

Free Energy made love to the past last night playing its third generation version of that all-too-familiar classic rock sound. St. Louis fans energetically danced, displayed rock hands and sang along at the Firebird last night.

If Stephen Malkmus would have started a classic rock band rather than starting Pavement, it might have sounded like Free Energy. Powerful rock riffs, as glam as anything from the '70s, carry this Philadelphia-based band. Fans of Thin Lizzy or Cheap Trick will want to hear Free Energy's brand of straightforward, no tricks, Marshall-and-Gibson rock & roll.
