Bubbles in bread

Toast
I am interested in baking a rustic bread with huge holes or bubbles and a thick crisp crust - any recipes come to mind? I have tried several chabatta bread recipes which come close but I'm looking for larger bubbles.

Peter Reinhart's The Bread Baker's Apprentice would be a excellent place to start.

In addition to great recipes, you will learn how to achieve that open crumb you are seeking.
