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.

Two weeks after announcing the departure of bassist Kim Deal, the Pixies this morning surprised fans with the release of “Bagboy,” the band’s first new song since 2004 and one that sounds like may feature the backing vocals of the group’s now-former bassist. But it doesn’t.

The Pixies this morning announced that bassist Kim Deal — who has spent much of this year touring with the reunited Last Splash-era lineup of The Breeders — has left the band , and, in a statement attributed to Black Francis, Joey Santiago and David Lovering, say “we will always consider her a member of the Pixies.”

Fans of Black Francis who plan to see the Pixies frontman’s solo-acoustic show in New York City next week who are older than 30 — and let’s face it, that’s a lot of us — might want to consider something they haven’t done in a couple decades: investing in a fake ID. Tickets are $15 cheaper for fans 30 and under.

Last night at New York City’s Terminal 5, the reunited Dinosaur Jr celebrated the 25th anniversary of You’re Living All Over Me by playing the 1987 album in its entirety and then enlisting members of The Smiths, Pixies, Sonic Youth, The Replacements and The Melvins to help blast through a second, career-spanning set.
