The Far Out Casual Collection is Online 

Our webstore is now up and running.  We've got T-shirts and sunglasses available.  Downloads are available for purchase from our Recordings page.  You can buy our LPs and CDs from Revolver/Midheaven.  We're saving up money to record right now so remember anything you buy helps us get one step closer to the next album.  Thanks for riding our cloud. 

New LP "Heady Mental" Out Now 

Our new album "Heady Mental" is now available in stores and online.  You can purchase vinyl and digital files from Revolver/Midheaven.  The songs were written in 2007/2008, recorded in 2009, and mixed in 2013.  Thank you for your patience.  We are planning on recording another album next year. 

Record Release Shows 


We've got two record release shows coming up to celebrate Heady Mental!  Thanks to Alan Forbes for his radical imagery.

New Album Out Soon 

Mammatus is pleased to announce the upcoming release of our long awaited third album, "Heady Mental." It will be released in the coming months by Spiritual Pajamas. The album was recorded in periodic bursts of energy over the last five years in our various dwellings around Santa Cruz County. We heard the test pressing the other night and had a group hug afterward, it feels really good to have it all over with. Thanks everyone for your patience.
