Carl Palmer: Art Showcase

I don't have reliable information about a musical artist specifically named "Carl Palmer: Art Showcase" in my training data. However, Carl Palmer is a renowned progressive rock drummer best known for his work with Emerson, Lake & Palmer and Asia, celebrated for his technically virtuosic drumming that helped define the sound of 1970s art rock. If "Art Showcase" refers to a specific project or persona, I'd need more context to provide an accurate biography.
