Addison Groove Projects Rob Marscher will debut his side project The Future Impressionists at the Blue Note on December 18. Part of the jazz-clubs Late Night Groove Series, the keyboardist will perform arrangements of Impressionist French music from the beginning of the 20th century plus some Russian and American music written around the same time. The rest of the night will focus on covers of rare funk tunes, live reworkings of DJ music and a few new, original cuts. Tickers to this 12:30 show are $8.
