The album's success coincided with Imperial Records picking up "The Progressive Blues Experiment" for wider release. The same year, the Winter trio toured and performed at several rock festivals, including Woodstock. With brother Edgar added as a full member of the group, Winter also recorded his second album, "Second Winter", in Nashville in 1969. The two-disc album only had three recorded sides (the fourth was blank). It introduced more staples of Winter's concerts, including Chuck Berry's "Johnny B. Goode" and Bob Dylan's "Highway 61 Revisited". Johnny entered into a short-lived affair with Janis Joplin, which culminated at a concert at New York's Madison Square Garden, where Johnny joined her on stage to sing and perform.
