One of Pink Floyd's legendary concerts took place at the Hollywood Bowl in 1972. David Gilmour hadn't been back on that stage or even in the venue since that night until Thursday (3/24) when the former Floyd guitarist staged a muti-media rich performance that used the entire backdrop of the shell as a canvas. The effect was similar to an IMax experience. With only four cities on his itinerary, Gilmour's first tour in over a decade is a tough ticket. Fans lucky enough to get one of the Bowl show also got to see David joined by David Crosby on a few songs.
