Up-and-coming hip-hop artists in this city are always complaining about how Kansas City's corporate radio stations don't play their homegrown releases. Instead of complaining, they should be sending their (edited for radio) tracks to Mz. DeShai Hampton, DJ Kiz-One and Lonnie "Luv" Porter at KKFI 90.1. They spin local tracks and national jams from 8 to 10 on Saturday nights, broadcasting live from the no-frills little studio above the swank Bluestem restaurant on Westport Road. On those Saturday nights in the studio, there's no divide between backpack hip-hop and gritty crunk music -- if it's clean, it gets played. The highlight every week is the Show-Me Showdown, in which callers blow up the studio's phone to vote for their favorite of two local artists' tracks. So while corporate radio plays Lil Wayne and Nelly Furtado 12 times an hour, names such as James Christos, Netta Dogg, the Soul Servers, Jae Casino and DJ Ataxic move from obscurity to local fame on 90.1. That's homegrown progress.
