July 9, 16, 23, 30. Hudson Valley bassist Rich Syracuse and drummer Jeff “Siege” Siegel have been playing jazz together for years, perhaps most notably with pianists Lee Shaw and the legendary Mose Allison. But they’ve also been active independently of each other; Siegel leads his own on again/off again quartet, and Syracuse has performed in a duo with Shaw and with Medeski, Martin & Wood keyboardist John Medeski. Lately, the rhythm section has been holding down a weekly residency at Catskill Mountain Pizza Company that sees them with different guest players every session. Here’s the rundown of their accompanists this month: organist Pete Levin and guitarist Pete Einhorn (July 9), pianist John Esposito (July 16), singer-pianist Nina Sheldon (July 23), and a “very special” keyboardist TBA (July 30; check website). 8pm. Donation requested. Woodstock. (845) 679-7969; Facebook.com/catskillmountainpizzacompany.
