Digitally remastered edition of their third album that includes a 19 minute tour de force, "Parthenogenesis", which displays the quintet at their most experimental. Also featured is their incarnation of Henry Thomas "Bulldozer Blues" where singer Wilson retained the tune of the original song, rewrote the lyric and came up with "Goin' Up the Country", whose simple message caught the back to nature attitude of the late 60's and went to number one in 25 countries around the world.
