My mistake. After making the post last night, I found a double bass performance online by Barry Levinson of the Los Angeles Philharmonic; a Vivaldi Sonata. It was indeed very beautiful. I can see plainly that it was the player on my side last night, not the double bass.
We have worked frantically all day long, skipping lunch and proceeding with intensity to finish the data portion of our demo catalog. We still are not done. I’ll be back to work tonight again.
