Best busking in Phoenix...like anyone would brave the 80 degree nightime temps....:)...is actually in Tempe. You have to have a permit, but you don't have to audition. Here's the catch. You can't sit on the sidewalk. We actually have a law that says you can't sit on the sidewalks in Tempe!
Too many of the Sunshine Kids, or whatever they are calling themselves, camp out on the sidewalks and make foot traffic difficult. So the city passed an ordinance about not sitting on the sidewalks.
Bring a stool.
And you can do VERY well here. Especially weekend nights.
