I expect this group to go over most kiddies heads, but I think this group could really work:
Drums: MP
Bass: Sean Malone
Guitar/head songwriter: Nick Van Dyk
Keyboards: NVD again
Vocals/secondary song writer: Zac Stevens
It would be heavy, have a capable singer, a great and a good song writer.
Also, we'll never see it happen, but a MP / Devin Townsend collaboration would be awesome.
