Lots of Washington-area alternative-rock fans are dismayed over the last 24 hours at the sudden demise of the legendary station WHFS (never a ratings legend, just a legend) to make room for “El Zol,” a Spanish-language FM station. While the “HFStival” had become a big concert date in the last ten years, since the rise of grunge the station had become more and more indistinguishable from DC-101, which used to be the Led Zeppelin-Aerosmith station to HFS’s Clash-Talking Heads-REM sound. Still, the whole switcheroo, complete with lectures about how Spanish-language stations are a “growth market” and serve an “underserved” audience, can make you want to send money to Tom Tancredo. (Speak English, this is America, Jack!) The washingtonpost.com “wake” for HFS is here.
