CHICAGO TRANSIT AUTHORITY LIVE! at The Fillmore West Aug 17, 1969 - South California Purples

Formed in Chicago in 1967 and barred from using its original name, the Chicago Transit Authority, by that agency's legal-eagles, the original septet relocated to Los Angeles in 1969, hired hard-driving James William Guercio as manager, and launched its meteoric jazz-rock, soft pop/rock career.
