Rising Seattle alt-country artist Sera Cahoone and I just conducted a lovely interview over coffee for an upcoming No Depression profile. Apropos of her slot at the Block Party on the Neumo’s Stage at 5:15 on Saturday afternoon, she says she’s “very excited” about the gig. Any surprises in store? Yes. At least one new song besides selections found on her self-titled debut CD. “And maybe a cover.” Of? Give us a hint. “Um… R.E.O. Speedwagon.” When pressed for details (i.e. “which one?”), Ms. Cahoone squirmed, but said it would all get ironed out at band practice tonight. “I haven’t mentioned it to them yet.” Requests, anybody?
