Phil Lesh changed my life.

Phil was foremost an improvisationalist and taught me, all of us, Hart wrote.

All those years we all rode the third rail together creating something that cannot be defined in words.

He had wisdom, was older and showed us the way.

Phil Lesh wasirreplaceable, the band wrote.

In one note from the Phil Zone, you could hear and feel the world being born.

His bass flowed like a river would flow.

It went where the muse took it.

He was an explorer of inner and outer space who just happened to play bass.

He was a circumnavigator of formerly unknown musical worlds.

Harts tribute continued, Later he became first and foremost a family man.. His sound is indelibly embedded in my mind as is Jerrys sound… and always will be.
