Should be interesting. The fact that iHeart could lure away 4 long-time Entercom personalities is significant. Obviously Curtiss Johnson is a big factor here.
I noticed iHeart Radio operates several other rock stations with "The River" brand. They all seem to have a fairly wide playlist, 70s thru 00's, nothing too hard. Essentially a rock-oriented Jack FM. This would be a smooth transition for 93.7. Retain a good portion of the Jack listeners, gain the Dog/Joe fans from KRXQ, and chip away at KSEG with a wider variety of rock.
Sounds like the new format and hosts will debut on Monday April 3rd.
