It's not every week that one of the crowned kings of college rock royalty decides to spend one of their off-dates in Little Rock. It's even rarer that they decide to use it to play a solo show. But this Monday, White Water Tavern hosts Ken Stringfellow, the cult songwriter behind power-pop heroes The Posies. Alone, that contribution to music warrants a big-ass gold star, but add in the six years he spent in R.E.M., the great American band, and the 17 years he's spent with Jody Stephens and the late Alex Chilton as part of Big Star, the greatest American band, and you've got a sterling music icon. The man, in the middle of a tour with The Posies and Brendan Benson, trades in arena stages a tiny platform this Monday night. Expect a packed house of power-pop acolytes. Locals Isaac Alexander and Brian Frazier provide support with a couple solo sets.
