The Genealogy of Pop/Rock Music was recently mentioned in a few blogs including:

NOTCOT.org, a design community site that accepts examples of all facets of design. “NOTCOT.org was launched May 2006 to fill our need for a place to collect and share fascinating images/links.”

PagePlane.com Blog, “Innovative and interesting examples of graphic design, web design, illustration, typography, and marketing from designer Chuck Green”

Both sites are well worth a visit.
