certain artists & groups open for tech regionally on the regular. for instance... cool nutz, dj chill and posse' will most likely be with them for the oregon, washington and california shows like they were last year. many times a venue will have a local artist or two open for them. critical, i believe, will be on the entire tours roster of shows, otherwise some will see cazualty and potluck in the midwest region. not all "opening acts" are chosen by tech or strange... so dont get it twisted if someone comes out suckin balls.
