IF a music-act is EVER shown, then I hope it WOULD BE...
Michael Iceberg!! Before Mr. Iceberg performed on Johnny I saw him give a small concert at Yavapai College in the auditorium or gym. Back then he worked at Disney World and had a synthesizer setup in the shape of a pyramid. The pyramid had lights and gave off smoke that was more like cold dry-ice than smoking type of smoke. So more like vapor or steam, but cold instead of hot.

I own a copy of his album Michael Iceberg: "Does It Live".
I'll let you know when I come-up with a new signature, .
