Ryan Adams & The Cardinals Bassist Dies

Chris "Spacewolf" Feinstein, bassist for Ryan Adams' former backing band, The Cardinals, has died.

Feinstein, 42, passed away at his home in New York City, and his cause of death is still unknown.

"This is the saddest day of my life," Cardinals drummer Brad Pemberton said in a statement posted on the Lost Highway Records website. "I lost my best friend today... things will never be quite the same."

Feinstein officially joined The Cardinals in 2006 following the departure of original bassist Catherine Popper.

Feinstein's first disc with the band was 2007's Easy Tiger, which was billed as an Adams solo disc but featured The Cardinals. He also played on 2007's Follow The Lights EP and last year's Cardinology.

Feinstein had also worked with Moby, Santigold, Fat Joe, Albert Hammond, Jr., Minnie Driver and contributed his musical and production talents to the I Am Sam soundtrack.

Adams left The Cardinals in January because he wanted to take a break from making music. Adams has been suffering from Meniere's disease, an inner ear disorder that affects hearing and balance.
