I've seen him several times over the years. Always a knock out performer.
"I Walk on Gilded Splinters" (Gilded splinters being rays of starlight) from Gris Gris is one of the most astonishing and daring pieces conceived and recorded, a 90 degree turn from anything recorded previously, even for the wild 60s. It positively lit up late night underground radio in the late 60s. "Walk through the fire, fly through the smoke, see my enemies on the end of a rope". Not exactly peace and love, but Mac conjured it his way.https://www.youtube.com/watch?v=kWvdO3l4_P8
He made many, many more wonderful works.
A truly great, one of a kind musician, but much more than that. He was dedicated to keeping great legacy music and culture alive for future music lovers.
"Goin' Back to New Orleans" is an amazing 1992 collection of 100+ year old songs that would never get airplay today but are wonderful and amazing. Well worth looking for, among many others.
Keep walking on those splinters, Mac.
Another giant gone. Who will step up?
