Thanks Dave. I might not have been clear about #1. What I was saying was that if you stay on A major pentatonic when the D chord comes around, you are solo-ing with the notes A B C# E F# against a chord that has the notes D F# A C. So the video I watched, if I understood it correctly, was saying that this can produce some real nasty sounds on account of the C# (in A major pent) being sandwiched between the C and D of the D7 chord. I need to get a looper so I can evaluate some of this empirically, in person, with my own ears. Anyway, I'll be there for the live stream for sure.
