303 exists at 303 High St Northcote. It's been happily existing there for the last 10 years or so. That's way back when there were more second hand furniture and vacuum retailers on High St than pizza shops and night spots.
Ever since its inception, 303 has supported the live music scene, since that's what its inception was all about. A quality, no frills venue, that gives musicians and artists a place to be seen, heard and talked over the top of.
