I learnt recently from one of my teachers that Larry Schultz, the founder of Rocket Yoga, passed away on February 27th 2011.
I don't practice Rocket Yoga, but from what I understand, it's supposed to be a kind of "accelerated Ashtanga". The Rocket Series (there are three: Rocket I, Rocket II, and Rocket III) begins with Surya A and B and closes with the traditional Ashtanga finishing sequence, but incorporates postures from the second and third series into its sequence.
As I said, I don't practice Rocket Yoga and I've never taken a class with Schultz, so I can't tell you more about Schultz and his work beyond what I said above, but he sounds like a really dynamic and wonderful teacher, from what I've heard about him from people who've studied with him. So the yoga community is one wonderful teacher less. Please remember him in your thoughts, prayers and intentions.
