It also matters a lot what you're into. I haven't played at/been to a show at modified in years, I have no idea what goes on there. The Yucca will hurt Phoenix in that bigger all ages shows typically at the phix will likely be in Tempe now, but good. The Phix sucks (thanks for ruining Trap Them for me). Places like Trunkspace will continue to do well though, I'm sure.
YEA! i am not very psyched on shows at the Phix.
Really, what is the difference between Tempe and Phoenix as far as shows, they are a couple strip malls and a freeway ride away from each other, and most people have to commute across the valley to go to shows anyway, Its the VALLEY music scene. Too bad Tempe and Downtown Phoenix aren't sperated by industrial plaza's and an airport, but they are. Like Mikey said, you go where the show is.
I dont think its the "phix" that is not liked. Its a rad place and a cool room.
Just sayin!
