My wife and I and friends enjoyed Music Walk downtown Friday -- and discovered a local performer who's worth listening to again, an artist who goes by the name of Kosh, pictured, (which sounds like Kosher only Japanese-American rather than Jewish). He was performing in the Parkside building to empty seats when we arrived. We'd heard folk hillbilly music at Java on Fourth and Celtic music at All Things Irish. We planted ourselves for the rest of the evening when we heard Kosh's rendition of Rod Stewart's "Maggie Mae." He'll be playing at the Wine Cellar (7 p.m. Wednesday), Daanen's (6 p.m. Friday), and Moose Lounge (9 p.m. Friday and Saturday) this week.
