WHRB might have some shows...WGBH has jazz weeknights from 7 pm to 5 am according to their schedule,
as well as some blues (Sat nights) and Jazz Gallery weekend nights.
Mood Swings--Sun 3-6 pm WMWM 91.7 Salem (For blues, the Juke Joint Sun 12-3 pm. Yours truly
is on tomorrow and on 7/30)
I think there may still be some jazz on the Cape, maybe on WQRC 99.9, WMVY 92.7, and WOMR 92.1 out of
Provincetown (which can also be picked up across the bay in Plymouth)
WQRC: Sunday jazz brunch, Sunday 9 am-noon
WMVY: Sunday Morning and All That Jazz
"Sunday morning has its own rhythms and cadence. The alarm clock is off, the coffee is on and Dave Kish plays the brightest lights from the full spectrum of jazz, from 6 to 10am."
WMVY is at 92.7 and I think they have a repeater somewhere
