Voosh,
The 2nd video was in part for you, so that you could see Bo Ramsey at work.
As to the CDs, I've always tried to support the musicians, especially the ones who are still earning their chops in the bars, restaurants, and clubs. Over the years, I've understood that me and a few other people buying the CD on any given night may have an impact on what's for dinner tomorrow. I always buy the CD.
