The Night
A monthly Sunday-afternoon open mic at the Brolly Fermentarium, the live-music room attached to Brolly Brewing's Horsham taproom. It runs on the second Sunday of the month from 17:00 to 20:00. The Fermentarium is a proper performance space rather than a corner of a bar, so the night suits full acoustic sets as well as single songs.
