I have 3 tickets for this Friday's concert at Heinz Hall at 8:00,  $50 apiece.  The show features The Machine - a tribute to the music of Pink Floyd  (http://www.pittsburghsymphony.org/pghsymph.nsf/0/d6fd742143a472668525758b00591184!OpenDocument&Click=).  We'd love to be able to go, but another commitment has come up. Please reply to jmsutara@yahoo.com if interested.
