Mike Breen at Citybeat's Spill it Blog has a long post on local musicians doing commericals. He pulls together both local and the national acts doing this, in particular local bands Buckra, the Newbees and Whitney Barricklow. The meat of the post comes from analyzing the message boards at local music websites. If you have not bee to such sites at cincymusic.com or neussubject.net, then you don't know how volatile and often just insane some of the posters can be.
Throw Buckra into the mix and you are going to get a flame war.
For those who don't know Buckra, www.buckra.com, they are a popular local band that plays original pop music with a blues/jazz feel to it. They are not a stare at your shoes type band, they are professionals. They play often, show up on time, know how to tune their instruments, and begin their shows on time. They are popular and get grief from those who are a lazy ass musicians because they don't write "serious" indie music. That is no reason to bash them for making a living and getting break with the Gold Star commercial.
Side Note: My title is not a slight on Mike. I am a big Who fan, so I thought I'd pick a song title to mimic. "Mary-Anne with the shaky hands" won out. Yes, it is from the Who Sell Out album.
