Who’s ready to feel just a little older than they may already be feeling?

Positioning itself as “Classic Rock Redefined,” Sacramento’s KQJK 93.7 (known as JACK-FM) has officially launched its newly rebranded format under the name “The River.”

The station’s new focus will include hits from the late '70s, but will focus much of its format on the early 2000s with core artists including Aerosmith, Green Day and Red Hot Chili Peppers.

The station’s parent company, iHeartMedia, is replacing the old format -- which was a “classic hits” station focusing on bands like Led Zeppelin, the Eagles, Fleetwood Mac and others of a certain generation.

The River will continue to feature longtime Sacramento personalities: "The Dog and Joe Sho" was hired away from a competitor for the station's morning time slots, then Monica Lowe -- who's been in the local radio market since 1988 -- takes over midday hours and Derek Moore, formerly of "The Eagle," is host for the evening.

Nationally syndicated personality and former Motley Crue member Nikki Sixx can also now be heard on The River.

So, who's idea was it for iHeartMedia to replace the JACK-FM format and go this way?

iHeartMedia Vice President Curtiss Johnson is the man behind the decades-long success of stations "The Eagle" and "98 Rock." In his new job he's taking the best of his old stations, plus adding some of his own spin, to "The River."
