Ya have forgotten the 80's Roots Rock/ Power Pop band: the Outnumbered (Alisson Krauss actually played a fiddle on one of their songs when she lived here).
And the essential Lonely Trailer (80's/ 90's Alternative Rock).
And the new artists such as: Dank, Eleni Moraties, and Cougars.
And I'm ashamed of the early bands that made it big back in the day such as: REO Speedwagon and the short-lived, but the crappy progressive band called Starcasle.
Although, Hum kicks arse and the others are already mention.
