The band posted a full statement on their official website, including that the reason is "due to a severe illness in one member's family and Brian's decision to move to San Francisco come December."
But before that, the band is planning two final shows with the full band performing and added:
Letting go of this is hard for all of us, but it's something that due to the circumstances at hand, has to be done. Please come celebrate our last two shows as a composite of good friends getting together to play music.
The dates will take place on October 17th at Schubas and October 27th at Ronny's. The is supporting their sophomore release, Parts and Accessories, that came out earlier this year.
