Simon Gallup, 61, made the announcement in a public post on his personal Facebook page, writing: “With a slightly heavy heart I am no longer a member of the Cure! Good luck to them all…” In response to someone asking if he was OK, he replied that he “just got fed up of betrayal.” More here.

Founding guitarist Peter Koppes has left Australian alt-rock legends The Church for the second time “to explore his own musical path,” bandleader Steve Kilbey announced on Facebook today, while also revealing the group is at work on a new studio album. Full details right here.

Just days after completing their first tour without original bassist Kim Deal, the resurgent Pixies apparently have decided to part ways with her touring replacement, Kim Shattuck of The Muffs, who took to both Facebook and Twitter tonight to announce she was “super disappointed to learn that my time with the Pixies ended today.”

Mike Peters last week addressed his departure from Big Country, thanking both the band and its fans “for a wonderful four years” without offering any reason for his split with the reunited group — which itself only has revealed to fans that “Big Country and Mike will now be parting ways” as it continues on as a four-piece.

In the fall of 2010, the surviving members of Big Country regrouped, tapped Mike Peters of The Alarm to fill in for late frontman Stuart Adamson and proceeded to tour the world, and record and release a new album called The Journey. Three years later, though, Peters is out of the band.

The Violent Femmes have only played a handful of shows since reuniting this past April, but the band’s already experienced a major lineup shake-up: Drummer Victor DeLorenzo — who promised the band’s Coachella reunion would be a “monstrous thing of beauty” — is out, replaced by Brian Vigilone of The Dresden Dolls.

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.”
