Haven't jammed on the playa with a trumpet yet... but I've had the good fortune of playing with Jimmie Wiz and China Rose... flute players, a tuba player (we were fooling around with Dueling Banjos... but the tuba guy was laughing too much... you had to be there), lots of guitars, sax and I can't count how many drum circles.
2 women singers... one who sounded like Joplin and another who gave me the chills doing scat.
Once I was walking and playing an old song that my grandfather from Russia loved... and a guy walked up to me and started singing it! Only on the playa!!!
Last year I jammed with a gypsy guitar player who was probably the best guitarist I've ever heard.... a bit scary.
Live music on the playa... love it!
