B.B. King Concert
I have tried on several occasions to use my Leica D-Lux 3 at concerts at this venue with no success whatsoever.  This was the first day and night of shooting with the Sigma DP1, a camera
that I am not all that familiar with, but the results speak for themselves. Perfect photos? No, but for the first time out and literally out of the box to get a shot like this is impressive to me.
 
This is B.B. King's backup band.. and these men can play. Excellent concert
