Gary Duncan was a founder member of the legendary San Franciscan band Quicksilver Messenger Service. Between 1965 and 1975 the band played literally thousands of concerts and attracted massive critical acclaim and along with The Grateful Dead and Jefferson Airplane were one of the most influential bands to come out of San Francisco in the sixties. Gary played on many albums released by Quicksilver Messenger Service including Quicksilver Messenger Service, Happy Trails, Quicksilver and Solid Silver. Although the band effectively split in the mid seventies Gary has quite often along with David Freiberg reformed Quicksilver Messenger Service and toured the world usually with Jefferson Starship which also numbers David Freiberg as a member.

For a period from the mid eighties through to the mid nineties and beyond Gary Duncan led his own band Quicksilver and released a number of albums. These albums are now being made available again once more at the behest of Gary Duncan having been unavailable for some time.

Live At Sweetwater is Quicksilver led by founding members Gary Duncan and also David Freiberg. Although a more recent recording of the band the current line up are as musically adventurous as the original band and really stretch out on songs like Maiden Voyage which clocks in at over eleven minutes and Inner City which breaks the thirteen minute barrier and certainly musically as good as anything the original band recorded or performed.

Whilst the current line up of Quicksliver Messenger Service continues to record and perform this recording has been unavailable for some time since its first release in early 2007 and this release will be welcomed by the large and dedicated cult following that Quicksilver Messenger Service retain.
