Painter was a Canadian rock band formed in 1970 in Calgary.
Their big hit "West Coast Woman", from the album Painter, was released in 1973.
Other bands that came out of Painter include Hammersmith, 451 and Prototype.
QSound was developed by Dan Lowe[1] after experimenting in a recording session that involved multiple microphones set up around a studio.
The technology was used on recordings in the 80s by Pink Floyd, Sting, Madonna and other noted artists and is currently being used in cellphones.
