I've seen Zoroaster once and was totally impressed, Kylesa about four or five times and am in love with them, and The Sword once and can totally agree with what you said about the crowd participation. The people at the Sword / Karma to Burn show I saw last winter just tore shit up for over an hour to The Sword - it was quite a fun show.
Glad you had a blast at this. Maybe give Zoroaster's latest album (Matador) a spin and see if you don't find something on there to like. I thought it was pretty good myself.
