Support bands

I remember when I saw Jamie Lidell assupporting artist of Bjork. I think I like his music now more than Bjork´s. And I remember seeing a great gig of the Eagles of Death metal in Prague and it was amazing and when they performed as the support band for Arctic Monkeys, I was not so convinced...
In general, support bands are great, but no matter how hard they try, they can never get the crowd crazy. I just saw Sky Larkin as support band to Les Savy Fav. Actually both bands were great, but I slightly preferred the support band. And they gave away free badges. I liked them, but in the end we bought merchandise from the Les Savy Fav. And I was left with a feeling of guilt, for having the choice and deciding to contribute to the already well off band rather than supporting what I actually liked more...
I was punished by karma for my act because my ear has been ringing since the concert (48 hours now). Why do concerts have to be bad for your health? Anyways, Sky Larkin will be back in December to support another concert. maybe I will go back and not give an awkward smile to the drummer selling their merchandise, but reach in my wallet....
Long live support bands!
