The Pixies have been rehearsing for their upcoming tour with new bassist Kim Shattuck of The Muffs in Los Angeles this past week, so perhaps it’s no surprise the band headed out last night for a last-minute, surprise warm-up show at the Echo — where the band debuted six of their new songs.

With their fall tour set to open next week with a club run in Los Angeles, the Pixies today released the first in a series of new EPs — a four-song set cleverly titled EP-1 that’s available as a digital download or on limited-edition 10-inch vinyl — and premiered the music video for one of those songs, “Indie Cindy.”

Over the past few weeks, the members of the Pixies — Black Francis, Joey Santiago, David Lovering and new bassist Kim Shattuck — have been treating fans to photos and video through a collection of new Twitter, Vine and Instagram accounts named “The Actual Pixies.”

The Pixies are now set to debut their new Kim Deal-less lineup at Chicago’s Riot Fest this September, joining a bill that includes The Replacements, Blondie, Violent Femmes, Mission of Burma, X, Dinosaur Jr and Peter Hook, among many others. The Pixies were added today alongside Joan Jett, TSOL and Suicidal Tendencies.

The Pixies today followed up last week’s free release of a surprise new track with more revelations, namely that the band is about to embark on a “massive global tour” to debut material off its follow-up to 1991’s Trompe le Monde with The Muffs frontwoman Kim Shattuck replacing the departed Kim Deal.
