If you haven't been to Kleinhans music hall in a while, tonight might be a good night to go back.  The Buffalo Philharmonic Orchestra will be playing the music of rock gods Led Zeppelin @ 8PM and its sure to be quite the event.  'Kashmir' alone would be worth the price of admission.  Tickets are only $29, although by now there might only be standing room tix left. Check out the BPO facebook page for an interview with 97 rock about tonight's event and the issues of playing rock music. On a side note, this is the BPO's 75th year. so happy anniversary BPO!
