If there's going to be Jam Sessions at TechEd this year, I'll be there. A couple years ago in Atlanta I had a lot of fun at the Jam Sessions, and this year should be no different.
In the past Microsoft rented out a bar, filled the stage with gear, and opened it to the public. There are a few regulars that show up, and I hope to be one of them. It's a real hoot. Ask Russ Fustino! He was there in Atlanta that year, and can attest to the par-tay rock-star attitude that was in the air.
So, if you see “Jam Sessions” on the extracurricular schedule somewhere, go and have some fun. Who knows. They may give me the microphone. :-)
