How many of us who are young or old enough to have started buying jazz in the 1970s still have a soft spot for 70s jazz twofer LPs? When I started buying jazz in the late 70s, my choices seemed to be either Columbia artists like Miles, Monk, Mingus, and Brubeck, who never went out of the catalog; Blue Note and Impulse! LPs in the cutout bin (those were the days!); CTI albums that I hated then (and love now, at least until 1975 and if Bob James isn't involved); and twofers on Verve, Milestone,
