Picnic - A Breath of Fresh Air is a sampler issued originally by the Harvest Records label, originally released in 1970 and is remarkable for including the full-length version of the unreleased Pink Floyd song, "Embryo". EMI as a record label did not generally have a reputation for taking risks; however, having seen that progressive music had become popular, the niche Harvest label was launched in 1969 to take advantage of that market. As with many record labels at the time, a budget-priced showcase album of their artists was produced. This was Picnic, and Harvest's roster of artists was large and interesting enough to support a double album retailing. The result was an eclectic mixture of traditional folk, hard rock, psychedelia and the wilfully obscure.
