From their website:
Armed with "Bagboy," the band's first new song in nine years, the Pixies will launch the first leg of what will be a massive global tour on Sunday, September 29 in Paris, France. This will kick off the first tour the Pixies have done in nearly two years, and will give them an opportunity to do something they haven't been able to do in two decades : premiere brand new Pixies songs, the first collection of new material since 1991's Trompe le Monde.
PIXIES ANNOUNCE FIRST LEG OF WORLD TOUR
I'm fairly certain there will be a new Pixies album. But I hope they have better material than 'Bagboy' up their sleeves. If the new album is a pale shadow of their original output I will find it impossible to see their ongoing reunion as nothing other than a cash-in job.
