I believe this video was taken at an outdoor concert at the Forum in Ontario Place in the summer of 1979. I was at that concert, having been a Bruce Cockburn fan for a couple of years at the time. I had never in my life heard a guitar played like this by anyone else, and Bruce inspired me to do my best to become a much better fingerstyle player.
This tune is called ‘Water into Wine’ and can by found on Bruce’s 1976 album ‘In the Falling Dark‘. The guitar Bruce is playing was made by Jean Larrivée and was one of the first ever acoustic guitars to feature a cutaway to allow the guitarist more access to high notes. In the 1970s most acoustic guitar builders believed you could not make an instrument like that without sacrificing tonal quality, but Jean Larrivée proved them wrong.
