I checked out Round number 48 at the Fremont Abbey Arts Center last week, and in case you’ve never been, it is, as its name implies, a round-robin, multimedia arts performance in which a handful of songwriters switch off performing their and each others’ songs, with a spoken word poet (or poets) thrown into the mix, too. To top it off, there is also at least one artist painting or otherwise creating visual artworks on the sidelines. Well, the Round has grown since its humble beginnings — there are now Rounds happening in other cities as well — and to commemorate this 50th Seattle show, it will be held at the very-classy Triple Door on Tuesday, July 7 with some well-known performers: Jesse Sykes, (pictured)Damien Jurado, and Buddy Wakefield. They’ll be joined by artist Scott Erickson, Easy Street muralist Glenn Case and a poet from Youth Speaks (not to mention some other mysterious “special guests.” If you’ve never been to the Round, it generally happens the second Tuesday of every month at the Fremont Abbey Arts Center, and the space tends to fill up; since this one’s at the Triple Door, it shouldn’t pack out quite so fast, but the noteworthy roster means that it might be wise to buy tickets in advance (they cost $12).
