It's been said that John Coltrane and Charlie Parker met for the first time at the corner of 18th Street and Vine. If you've neglected your civic duties and have yet to see the American Jazz Museum, it's closed today, but musically inclined types can still bring their instruments for the Blue Monday Jam at the museum's attached nightclub, the Blue Room (1616 East 18th Street, 816-474-8463). This week, sit in with — or sit back with a drink and listen to — tenor saxophonist Matt Otto and vocalist Shay Estes Drink specials include a $4 Blue Room martini and $3 beer, wine and wells. There's no cover on Mondays. The Blue Room opens at 5 p.m., and the jam (open to minors accompanied by adults) starts at 7.
