Been a loooong time. Not including small bar bands, I guess my last concert was Slayer in 2002, touring for "God Hates Us All", at the 930 Club in DC. Good set with new stuff and old classics, very loud. Ears were ringing the next day.

Awesomeness of band - 10/10. It's Slayer, they do a great live set.
Quality of beer - N/A, didn't drink, but the 930 has a OK selection
Quality of loos - N/A, see above
Quality of talent - 2/10, probably 10 girls total in the whole place
Quality of kebab/deathburger on way home. - 7/10, pizza!
