Just Rock Enterprises

Just Rock Enterprises' own website has a dedicated page titled 'Open Mic Night 3rd Thursdays @7pm,' with 2026-dated content describing the open mic at its Brentwood studio and instructions to sign up in advance (checked Aug 14, 2026) [s1]. This confirms it is a standing in-house open mic at the studio, not only a producer of showcases elsewhere, and pins the frequency to the third Thursday of the month.
