Cover art for Best Batch Yet lyrics by Captain Beefheart and the Magic Band

Beefheart giving praise to the best version of the Magic Band who are the "best batch yet" or about magic itself how illusions are made by stage magicians, either real or imagined like the finest pearls that are really cardboard balls. The lines about "done with dilgence from the inside ....." It could refer to the creative process itself, like making art or a poem.
