What a list!
A few years ago, I used to drive pretty long distances so I started downloading bass-related podcasts as I was (and still am) new to the instrument.
The podcast with Dan Lakland and Joe Osborn (Basscast #25 from 31-Jul-2006) blew me away.
I had no idea that Joe Osborn had done so much work on so many great tunes...and between the two of those guys, there seems to be very little ego getting in their way.
