RHH should be an awesome show.
These are both Portland Bands, and are nothing alike:
Horsefeathers - Like a chance to see Nick Drake in concert during some songs, Bob Dylan during others, and experimental folk\grass\rock during others. I saw them\him play a short set at the Portland Central Library and found myself leaning-in harder than any other show I've seen. Acoustic guitar, cello, violin, and saw are the typical instruments.
1 - Happy Valley, OR @ Pickathon Festival
2 - Happy Valley, OR @ Pickathon Festival
The Thermals - Stellar punk\pop-rock fusion; soaring, meloidc, intelligible and intelligent punk ballads that cover environmentalism, religion, politics. They turned down a $50,000 offer to use one of their songs in a Hummer commercial.
July 24 - Portland, OR @ Jackpot Records - 6pm, free, all ages
