The Eastport Arts Center’s weekly Sunday concert series returns to the EAC at 3 p.m. Sunday, Feb. 2, with Sánchez & Sánchez, a guitar and bass jazz instrumental duo.

The father and son team of Robert Sánchez and Ellis Zipperer-Sánchez will present an array of tunes from the Great American Songbook, including some straight-ahead jazz, and standards ranging from ballads to uptempo tunes, plus several in the bossa style. The duo will also feature singer Lauren Koss on a few numbers. A question-and-answer session will follow the music.
