Jimi Hendrix

According to the Janie Hendrix of the Jimi Hendrix estate there are decades worth of unreleased material which they intend to share with his fans in the near future!

Hendrix  who died in the 1970’s, after a career of four short but stupendous years is considered as on of the best guitarists that ever played. (duh, as if you didn’t know)

In a statement by Hendrix’s sister:

“We probably have another decade of music, including video. Every 12 to 18 months we’ll continue to have new releases and Dagger (Experience Hendrix’s label for live recordings) official bootlegs.”"Jimi was a workaholic. After Electric Lady studios was built he was able to record constantly for as many hours as he wanted to. It’s almost as if he knew he had only four years to accomplish everything that he did. We have an amazing amount of original masters, including a lot of material that hasn’t been previously released.”

Sounds good to me if it’s authentic and not overly mastered, nothing like some posthumous music from a rock legend!
