The 70s were an incredible period that produced many foundation music recordings. Hamish Champ has captured this explosive decade in a new book, 100 Best Selling Albums of the 70s.
I own 75% of the recordings listed in my collection. It was an exciting era where music sold in tonnage. Artists achieved multi-platinum sales (Platinum = 1 million albums sold). Arena rock became the new concert experience (the reason rock impresario Bill Graham closed his Fillmore East and West venues).
