A new album of unreleased songs by late legendary singer Jimi Hendrix, titled "People, Hell and Angels," will be released Tuesday.

Nearly four decades after legendary singer and guitarist Jimi Hendrix passed away due to drug overdose in September 1970, a new album of unreleased songs by him will be released this month.

The album will contain 12 tracks and will be released Tuesday. A preview of the album can be heard online at NPR's First Listen. They are also available for preorder on iTunes and Barnes and Nobles for $10.79 per CD.

"When I listen to 'Hear My Train a Comin', it feels almost ghostlike," said Janie Hendrix, Jimi's stepsister and CEO of Experience Hendix, about one of the tracks in the album. "It's so deep south of the universe and filled with the blues. When we transferred the tapes, my heart got so full I started to cry."

These unreleased songs were recorded by Hendrix's sound engineer, Eddie Kramer, beginning of 1968 as a follow-up to his "Electric Ladyland" album but were never officially released, until now. A preview of the entire album can now be streamed online.

"'People, Hell and Angels' is Jimi Hendrix's new album with twelve recordings which encompass a variety of unique sounds and styles incorporating many of the elements -- horns, keyboards, percussion and second guitar -- Jimi wanted to explore within his new music," the official statement on JimiHendrix.com reads. "'People, Hell and Angels,' presents some of the finest Jimi Hendrix guitar work ever issued and provides a compelling window into his growth as a songwriter, musician and producer."
