Chelsea Grin parts ways with Jason Richardson

Chelsea Grin has formally announced the departure of guitarist Jason Richardson, who joined the band in 2011. Richardson's departure comes as the result of "music differences," and he's since been replaced by Stephen Rutishauser. Here is the official word:

"We would like to welcome Stephen Rutishauser (Speeve) as an official member of the band. Stephen has been playing with us for over a year now and has fit perfectly in the band. Stephen has been a long time friend of the band and wrote the song Nightmares which was featured on Ashes to Ashes. "Along with the addition of Stephen, comes the departure of Jason Richardson. Us and Jason have split amicably, with the decision being based on musical differences and how we envision our next record sounding. Jason has been an asset to Chelsea Grin for years now, but will be focusing on his solo material and we thank him for his time with us. Jason recently launched an Indiegogo campaign to fund the new solo record. "Our new record will be out next summer and we promise you it will be our most extreme release to date. We are back."
