I've seen Peter a few times solo and with Genesis. Also with the Amnesty International all-star band (with Springsteen and Tracy Chapman) and once as a duo-bill with STING.
After the UP tour I also went to see Peter with the full Orchestra (New Blood Tour) which as a very unique experience indeed, loved "San Jacinto".
My first solo Gabriel concert was during the "melting face" tour on July 1980 at the Wollman Skating rink in Central Park New York.
The band wore all black jump suits and Peter emerged from the back of the audience singing his way to the front of the stage. The whole set list was only his material (no Genesis songs) from his first 3 albums. Incredible but David Rhodes and Tony Levin were already in his band. The drummer was Jerry Marotta and on keys it was Larry Fast. Excellent show, no special props but Peter always kept things interesting.
