Jeff Healey - While My Guitar Gently Weeps | 464 MB
This song, “While my guitar gently weeps”, is a version of a song by George Harrison, performed by the brilliant guitarist Jeff Healey. You can find it in the album “Platinum & Gold Collection” by The Jeff Healey Band, edited in 2004.
Norman Jeff Healey (March 25th 1966-March 2th 2008) has been a brilliant guitarist. His style mixed jazz, blues, rock…
He was born in Toronto (Canada). When he was less than 1 year old, he lost his sight due to a retinoblastoma (a cancer of the eyes).
Healey fought against this terrible illness all his life, until the cancer killed him when he was 41 years old.
Healey was a fan of John Lee Hooker, Muddy Waters, Clapton… Without a doubt, these artists were a big influence in his work. When he was only 6 years old, he made his debut.
We will never forget his powerful way of playing, with the guitar flat on his lap.
