Early Show

If you’re in the habit of dozing off around 7 p.m. and waking up at 3 a.m. to put on your steppin’ shoes, you probably know about the Mutual Musicians Foundation (1823 Highland, 816-471-5212). The speakeasy-tinged jazz venue is known for its dawn-welcoming jam sessions, which attract a mixed crowd of jazz cats and socialites who simply want a place to hang out after all the bars have closed. Those who prefer a slightly less punishing bedtime can rejoice in the Foundation’s 12 O’Clock Jump Radio Show, which tonight salutes Jimmy McGriff. Doors open at 11:30 p.m. for the free midnight show. The Late Night Jam follows.

Sun., March 29, midnight; Sun., April 5, midnight, 2009
