Throwback Thursday: Santana - Soul Sacrifice (live 1969)

Not sure why, but I've been listening to jam bands all day.  Probably had something to do with that mescaline comment I made in a plug I wrote this morning.  Santana's performance of "Soul Sacrifice" at Woodstock in 1969 is one of my favorite live recordings of all time.  It's impossible to watch the video without feeling the energy emanating from the stage.  The story goes as follows: Carlos Santana, having arrived at the festival many hours before he was scheduled to play, decided to indulge in a rather healthy dose of mescaline.  A few hours into the trip, a schedule change resulted in Santana having to play hours before their scheduled time.  In interviews after the festival, Carlos Santana recounted that he experienced the peak of his trip on stage.  He said that in his mind, the neck of his guitar was morphing into a snake and he had to use his utmost concentration to maintain control of it.  Just watch his face, and you'll see what he's talking about.
