We’re hearing word that Z104 has fired all of its staff and will be switching formats at some point before the end of the week. The tip comes from a local musician (Chris, from Full Minute of Mercury) who was scheduled to record there this week, and whose taping got cancelled in lieu of the news.

On air, the station seemed to be maintaining itself as “Z104 Washington’s Modern Music,” and the sounds of Peter Gabriel’s “Sledgehammer” indicated status quo; but nary a human voice was heard for about 20 minutes, just songs and pre-recorded messages. That was, of course, until the announcement was made moments ago: “As of noon today, 104.1 will become Washington’s Home of Classical Music, WGMS.”

It was right about this time last year that another local-music-friendly station bit the dust. We still miss you, WHFS.

Farewell, Z104, and hello WGMS.

UPDATE: Z104’s departure isn’t the only change to the local radio dial (as discussed by our trusty commentors). For a complete run down on the local radio station changes, visit WTOP News.
