"I think we could've done a new record or new songs," says bassist Robert DeLeo, "but how many times do you go to a show and you want to hear the songs you're familiar with, and then when that new song comes up, that's when you go grab a beer.
"I think new material will come probably after this tour, but I think we're mostly getting back to the stuff we know and the things that got us together in the first place."
STP has been apart for 10 years, while singer Scott Weiland has fronted the band Velvet Revolver and DeLeo and his brother, guitarist Dean DeLeo, have produced other acts.
The STP reunion tour kicks off May 17 at the Rock on the Range festival in Columbus, Ohio, and is due to wrap up at the end of August, after which Robert DeLeo thinks the quartet will concentrate on new material.
