Zia Diner holds its weekly Zia Diner Bluegrass Jam from 6 – 8 p.m. Tues. Aug. 26, 2014. That, as they say (who is they anyway?) is not news. What is news is that it is fun and it is consistent. So if someone is looking for some variety on the event calendar in Santa Fe, NM, there is always the consistent, constant, Zia Diner Bluegrass Jam.
