There are all sorts of milestones in this month's Jazz Roundup. The biggest deal comes from Wynton Marsalis, whose 50th birthday was celebrated with a pair of records that show the trumpeter's paramount cultural clout. How many other musicians' labels issue a birthday retrospective? How many people get to jam with Clapton to celebrate half a century? There's also the final take from iconic vocalist Etta James and the realization of Christian McBride's long dream to lead a big band. Those three are joined by James Carter's organ trio and some torch-y vocals from L.A. pretty boy Michael Feinstein.
