Returning to Los Angeles, Parsons sought out Hillman, and the two formed The Flying Burrito Brothers with bassist Chris Ethridge and pedal steel player Sneaky Pete Kleinow. Their 1969 album "The Gilded Palace of Sin" marked the culmination of Parsons' post-1966 musical vision: a modernized variant of the Bakersfield sound that was popularized by Buck Owens amalgamated with strands of soul and psychedelic rock. The band appeared on the album cover wearing Nudie suits emblazoned with all sorts of hippie accoutrements, including marijuana, Tuinal and Seconal-inspired patches on Parsons' suit. Along with the Parsons-Hillman originals "Christine's Tune" and "Sin City" were versions of the soul music classics "The Dark End of the Street" and "Do Right Woman", the latter featuring David Crosby on high harmony. The album's original songs were the result of a very productive songwriting partnership between Parsons and Hillman, who were sharing a bachelor pad in the San Fernando Valley during this period. The atypically pronounced (for Parsons) gospel-soul influence on this album likely evolved from the ecumenical tastes of bassist Chris Ethridge (who co-wrote "Hot Burrito No. 1 Your Toy" and "Hot Burrito No. 2" with Parsons) and frequent jamming with Delaney & Bonnie and Richards during the album's gestation.
