Here's Macrotonic on the hunt for beats. He knows some traditionalists seek out the 3/4 beat, and some afficionados seek out rare and exotic beats such as the 11/13. But for Macrotonic, you can't beat(!) a good solid 4/4 beat. The habitats where they are found are a delight to explore and there's often the surprise of a quality beatless beat which can be found in similar environs.
