Brief History of Bryston

Founded in 1976 by the Lanois brothers (including Grammy award winner Daniel Lanois) and Bob Doidge, Grant Avenue Studio is a recording and mixing facility based in Hamilton, Ontario, Canada that also provides mastering and tape transfer services. The hallowed rooms within the stately converted early 1900's Edwardian home on Grant Avenue have seen numerous recording legends such as Gordon Lightfoot, Bruce Cockburn, Ian Thomas, U2, Johnny Cash, Los Lobos and countless others. Bob Doidge became sole owner of the studio in 1985 and touts Hamilton as a cultural gem just Southwest of Toronto on the shores of Lake Ontario.
