Leading livetronica outfit STS9 has canceled the rest of its Winter Tour 2011, due to an illness in the ranks.  De facto bassist and leader David Murphy has been diagnosed with cancer, and will spend the next few months undergoing surgery and in recovery.  STS9 is schedule to play Mayan Holidaze this weekend, but will go on hiatus until further notice.

Here is the letter David Murphy posted to fans on the STS9 website:

Greetings Family,Friends and Fans,

I'm writing to share with y'all some news I've received recently. I have just been diagnosed with a cancerous tumor primarily in my sinus cavity (a type of internal skin cancer).  It will require extensive surgery followed by a few months long recovery periods. There will be some treatment for the cancer following also but at this time we aren't fully aware of what that will entail and at this time we are just focusing on the task at hand which is the surgery.

With this news comes a bit of bad news for our upcoming shows. We will have to cancel all of our upcoming shows in Feb and March in order to fully get after taking care of this little health issue to the fullest, and we will do just that. There is nothing more in the world I love then playing music and sharing it with all of you and we will continue to do it for a long time together and all I ask for is y'all's thoughts and prayers during this time of recovery!

We will still be performing in Mexico this weekend before my upcoming surgery, so for y'all down there?.

Let's do this?. Boom!

We'll send appropriate updates as we get them through out the process.

- Murph

We at The Untz extend our sympathies and good wishes to the greater STS9 family.
