Ray Edenton started his career in radio in 1946 and playing bass fiddle with the Crazy Joe Maphis early 50's group the "Corn Crackers" .
Later he became a major country music and bluegrass sideman guitarist in the Nashville studios from 1953 to 1991, with 15,000 sessions on the clock he had time to experiment different instruments and tiple was one of those.
At the end of the 50's bluegrass producers search for new sounds and instruments melted flavors: mouth harps, pianos, accordions and sometimes tiple follows the slide guitars and the sacred "banjo mandolin fiddle guitar" combinations.
Between 1959 & 1962 he's credited on tiple for 3 sessions :
in 1959 with the Osborne Brothers , then for the 1959 Mac Wiseman "Great Folk Ballads" album and in 1962 again with Wiseman for "Bluegrass Favorites"
On two of the Osborne Brothers tunes the tiple is well recorded, nice open playing reveal the typical sound on songs intro and counterpoint , Ray is obviously an accurate tiple pick player playing arpeggios and clean chords rolls.

"It's just the idea" :
Thomas Goldsmith talk about the Osborne sessions in "The bluegrass reader":
On Mac Wiseman "Great Folk Ballads" in a more "high" mandolin sound and playing he echoed and counterpoint the two guitars, one played with nice middle tones embellishments probably by Chet Atkins .

"Little Moses" :
On "Bluegrass Favorites" it's quite hard to sift out of the mix the tiple parts, Benny Williams the mandolin virtuoso is clearly in front of the band for most of the tracks.
