(My first post, Hi everyone!)
I'm just a few hours from Aspen... wow, I'm tempted!
In addition to the improv, I see a 'Puppet Master Class' listed in Bonus Shows...
Enjoy a rare behind-the-scenes peek at the inner workings that transform a puppet into a lifelike person. The Jim Henson Company’s world-renowned puppeteers Brian Henson, Bill Barretta and Julianne Buescher, along with Groundlings alum Patrick Bristow, invite you to witness through demonstrations and audience participation the chaos of puppet improv from a performers’ perspective.
I can't post URLS until I've made 10 posts, sorry...
Go to guide.hbocomedyfestival.com, then select 'Bonus Show' to find this.
