NEW YORK (AP) Recording engineer Eddie Kramer recalls the hair on his neck standing up when he heard Jimi Hendrix record in 1969.
He says the same thing happened again when he heard the tapes 48 years later.
The upcoming album "Both Sides of the Sky" will feature 13 Hendrix tracks, ten of which have never been released.
Guest musicians include Johnny Winter and Stephen Stills.
The album will come out March 9.
It's the third in the trilogy that also included "Valleys of Neptune" in 2010 and "People, Hell and Angels" in 2013.
Kramer says the Hendrix estate still has some live footage of Hendrix that it plans to release.
