Hello Carolyn McCoy,
I would contact both places, as it sounds you have done, then go with my gut feeling. You may have made your decision by the tone of your question and research.
I do not use one of these programs, yet; but, do not want your question ignored, either.

Before making a decision, take at least two of each class if you can, preferably with different instructors. My experience with Pound wasn’t good, even though I took it from 3 different instructors. The form wasn’t great and there was a lot of shoulder rounding by participants to get down to the floor and in seated V; that just perpetuates our typical bad posture from over-sitting. I’ve only had one Drums Alive experience, at an IDEA sesion, and it was very fun.
