Pathways to Unknown Worlds was originally issued on LP in 1975 as part of Sun Ra's ill-fated and short-lived ABC/Impulse! Records partnership. ABC offered an ambitious deal that promised dozens of remastered editions of Sun Ra's Saturn back catalog along with a slew of new titles. The launch fizzled shortly after liftoff, but not before introducing two vital albums to the Ra catalog: Astro Black and Pathways. (Astro Black was reissued in all formats by Modern Harmonic in 2018.)
