About Café 635
Café 635 takes its name from the elevation of Great Blue Hill — 635 feet above sea level — and the sweeping views that come with it. Located at the summit of Blue Hill Observatory & Science Center in Milton, the café offers a one-of-a-kind setting for live music: open sky, clean air, and a horizon that stretches across the Greater Boston landscape.
The Open Mic series brings together local musicians, poets, storytellers, and first-time performers in a welcoming, informal setting. Whether you’ve been playing for decades or just picked up a guitar, the stage is open.
