As a few of you may have heard, my great friend and inspiration Rob Wasserman has been hospitalized and is facing a serious struggle. I hope that we can all pause to send him and his family the strength and support to face these difficult days. Rob and family, my thoughts, heart and spirit are with you today.

Wasserman has n incredible list of collaborators throughout his musical career, including Lou Reed, Jerry Garcia, David Grisman, Van Morrison, Aaron Neville, Brian Wilson, Neil Young, Jackson Browne and more. We wish him all the best.
