In 1971, Ehart and Hope left the group, and Livgren reworked the band and continued it under the name Kansas. (This group later became known by fans as Kansas II and is the lineup that re-formed decades later as Proto-Kaw). Kansas II continued to perform Livgren's original works, which fused experimental rock with psychedelia and jazz. During this time, Kansas II recorded a demo cassette that was released commercially 30 years later. Kansas II generated a loyal fan following, and the built-in audience helped the band secure concert bookings. However, financial problems plagued the band, and after a record deal with Jefferson Airplane's label failed to materialize and an old school bus broke down while the band was on the road touring, the band dissolved in 1973.
