Charlie Haden

When you listen to a symphony orchestra, and the basses don't - there's no bass part, there's not that much depth. That's why I'm attracted to the instrument, the bass. It brings depth. It's like playing in a rainforest.

I wanted to do 'Oh Shenandoah' because that's the town I was born in - as a tribute to my mom and dad for giving me all this music. I don't really sing this as a singer, because I'm not a singer. But I wanted to do it for them.

In L.A., I played with Joe Pass and Gabor Szabo. Mick Goodrick plays guitar in the Liberation Music Orchestra, and he's a real special player. Then I did a duet concert with Jim Hall at the 1990 Montreal Festival.

It's a wonderful profession, and it opens lots of doors, and I think it's quite right that people can accuse actors and actresses of being dilettante, but you learn on every job, whatever it is, the process moves you on in some way, and yeah, I want to expand my knowledge of our existence, I suppose.
