Fans of both bluegrass, classic country and original country rock should check out California-based Sierra Records and the company’s latest release, “Sixties Transition.”

The CD features “rare studio recordings from the archives of noted L.A. producer and the father of the folk-rock sound, Jim Dickson,” according to Sierra’s Web site.

“Sixties Transition” features cuts by the The Byrds, The Dillards, Gosdin Brothers (yes, that would be Vern “The Voice” Gosdin and his late brother, Rex), Dino Valenti, David Crosby, The Hillmen, Hamilton Camp and others.

These are rare recordings from producer Dickson’s audio archives based on the old Together Records LP, “Early L.A.,” according to John Delgatto, Sierra’s founder and owner.CD highlights include the first, never before released recordings of the Sixties peace anthem, “Get Together” by its composer, singer Dino Valenti (later of Quick Silver Messenger Service); and Hamilton Camp & The Byrds with a newly discovered 1965 studio recording of Dylan’s “The Times They Are A Changin.”

Also included is a rare instrumental recording of “Charisma” by David Crosby and jazz musicians Bud Shank and Joe Pass and never before released bluegrass-rock recordings by the original Dillards, who perform “Each Season Changes You,” “Some Day You’ll Find” and “Don’t You Cry.”

Leon Russell and Glenn Campbell team up on “Jamaica Farewell” and “Stewball” while the Gosdin Brothers cut features “To Ramona.”

Sierra has also restocked what it calls an “extremely limited quantity” of “Gene Parsons — The Kindling Collection,” which features Clarence White. Sierra also has new additions to what it calls its “Collector’s Corner” of country rock and folk rock classics. Those new additions were acquired at auction when the defunct Tower Records inventory was sold.

Delgatto has quite a history with his Sierra Records label. Some of that history plainly shows on the label’s Web site with final sales of audio casettes and vinyl albums.

Sierra Records’ Web site has been in operation for more than three years.

“But it all began in 1969, while I was hosting a regular bluegrass radio show in Los Angeles, I recorded and produced my first record album, a local banjo and fiddle contest, which included such artists as Doug Dillard, Byron Berline, David Lindley and others,” the label founder says on the Web site. “Though only less than a hundred copies were made and sold, it began a long journey that continues today. Yes, the company is approaching it’s 37th anniversary of a dream.”

Delgatto said his dream was originally nourished by encouragement from Doc Watson, Clarence White and Gram Parsons. Since starting the mail order business, his customer list includes several music celebs, including Keith Richards, Stuart Duncan and Jerry Garcia.
