Bluegrass Concert. Fremont Abbey, 4272 Fremont Ave. N., 701-9270. 8 p.m. $10. All ages. There is quite a lot of pseudo-roots schtick music being made right now that's been labeled "bluegrass" simply for lack of better terminology. So sometimes, it's nice to step outside of the indie intelligentsia-approved-band box and check out some artists performing the traditional songs that spawned the best (Whiskeytown, Gillian Welch) and the worst (the Avett Brothers) of the past decade's formidable roots revival. This show at the Fremont Abbey features artists who specialize in that old-timey stuff: Boston-based Della Mae, Seattle bluegrass band Loose Digits and duo Cahalen Morrison and Eli West. You know, people used to grow bushy beards not out of irony, but because shaving with a strop and a straight razor was a pain in the ass. Do you even know what a strop is? I didn't think so.
