91-92db SPL is the peak level you listened to unless you had the meter set to "average" in which case this was the average peak level (and actual peaks may have been higher).
Rock concert levels typically run up to 105 db SPL average (although this will be average for some songs and not others...a good rock concert will always have a variety of dynamic range in the music, as consistantly high SPL's eventually lose their excitement and become tiring...music is all about contrast or dynamic range...many artists will do a little "unplugged" stuff in the middle of the show for example).
An unamplified piano can go to 110 db SPL. Enjoy!
