These are from the October 7, 2005 performance at Grace Cathedral in San Francisco, CA.
Stephen Kent is a very talented diggery doo artist who also plays a ton of other cool percussion and wind instruments. Paul Horn is a jazz flute player who dabbles in a host of other genres.
These are little 30 second clips taken with my little Casio EX-S3. All I was trying to do was capture the essence of what it sounded like to hear a diggery doo in Grace Cathedral. I was amazed at the quality of the sound.
