As rock’n’roll approached its sweet 16 birthday in the early 1970s, it was obvious that it had grown up quite a bit...with each passing year, rock was becoming more sophisticated in both sound and execution...the first wave of rockers from the 50s and 60s had grown up.....they were now better musicians and could do more than play simple three-chord songs....
