The Jam could use some love. I like the space, have fond memories of its various iterations since childhood and I like to see the right kind of shows there well-attended. Tonight has one such show. Absynth Quartet is playing two long sets starting at 9 p.m. Although not in my usual wheelhouse, I have always enjoyed this group and its ability to mix skilled musicianship with crowd-pleasing grooves. That's harder than you think. For a mere $5 you can own this experience for an evening and have its accompanying memories for a lifetime. Priceless, really.
