He was signed by Warner Bros. Records to release his first single, "Will We Meet Again", paired with "Tia Juana Ball", which was distributed in late 1960.

All of the songs were either written or co-written by Markley with composer Baker Knight, who later wrote "Shifting Sands" for The West Coast Pop Art Experimental Band on their second album, Part One, in 1967.

These rare compositions rested in obscurity for decades until they were included on the 2011 compilation album, The West Coast Pop Art Experimental Band Companion.

Many directors and musicians including Jeff Beck and Jim McGuinn of The Byrds were also present as guests in the sizable gathering.

The group reluctantly accepted Markley's offer, and The West Coast Pop Art Experimental Band was formed.

The band was able to produce a wide variety of music ranging from folk rock, to guitar-led freakbeat, and multilayered, avant-garde compositions.

Authorities attempted to arrest Markley on undisclosed charges involving two young women, but he temporarily evaded the law.
