The Five Points Jazz Collective has been a quirky and disparate presence in Madison’s music scene for over a decade. Serving as the house band at the Mason Lounge since it opened in 2010, the Collective is an extended family of local musicians from varied backgrounds. Playing a mixture of jazz old and new, the group has evolved over the years from an open jam into a stable quintet with an increasingly large repertoire.In its current incarnation, the group consists of Rin Ribble (violin and mandolin), Eric Shackelford (drums), Trey Grimm (keyboards), Kyle Rightley (trombone and euphonium), and Brian Grimm (bass and contracello). As Tuesday night regulars will attest, no two shows are ever alike. Listeners can expect to hear many styles including swing standards, modal jazz, latin jazz, pop arrangements, blues, and funk. The group performs at the Mason on the first Tuesday of every month.
