So here's a $0.50 review of this $10 show.
22-20's - Not bad. Detroit garage rock-y with a British flair. They only played 5 songs - one for each patron that was in the club at that point.
Jet - This band's sound can be summed up by a single piece of their equipment "Flying-V"
If AC/DC, Molly Hatchet and Grand Funk Railroad spawned, Jet would be the product.
Kings of Leon - Ehhhh...... They were much better in person than they are on record. But most of the songs seemed to sound same-y. The guitarist was proficient and the rhythm section had some chops. I think it's just not my style. But judging by the very young and relatively well-dressed crowd who seemed to know the words to all the songs, these (exceedingly ugly) cats may be going places.
