Arthur, a long-running side-project of MxPx featuring Mike “Arthur” Herrera, Tom Wisniewski and former drummer Yuri Riley along with their former tech Neil Hundt, have announced they will be calling it quits after a decade together.

“Arthur was never a full time touring band, but we were a band none the less, which is why we're formally BREAKING UP,” said Herrera. “It just doesn’t make sense to keep doing nothing, so we’ve collectively decided to pursue separate creative endeavors.”

The band's debut album, 2010's Watch The Years Crawl By, has become their final material.

“We want to thank all of you that listened to our music and supported Arthur throughout the last decade,” said Herrera, Edmund, Alexander and Zane. “We created music for you, and the best part is that our music will never die!”
