John challenges me to "sort through the blizzard of music you love and offer up those most significant and most impactful as your life unfolded, and perhaps a note as to their impact." I am undone by the impossibility of this, but we have to start somewhere I suppose, and these YouTube bits will help a bit. But first, take a liesurely stroll through David Lindley's instruments (some of... he "admits that he has absolutely no idea how many instruments he owns and plays, having gathered them since the 1960s.") and then:

Minglewood Blues, 2 minutes in...

And then attend to what caused all the fuss in 1976 with the David Grisman Quintet record (Tony Rice's break at 1:10):

and see it done: David Grisman Quartet: E.M.D. (Eat My Dust)... Tony Rice break at 1:10
(a thousand things to say in explanation of this one)

and while we're here, you might enjoy this, from High Fidelity:
