1973 was the year rock hit its peak while splintering-just like the rest of the world. Ziggy Stardust traveled to America in David Bowie's "Aladdin Sane". The Dark Side of the Moon began its epic run on the Billboard charts, inspired by the madness of Pink Floyd's founder, while all four former Beatles scored top 10 albums, two hitting number one.

FM battled AM, and Motown battled Philly on the charts, as the era of protest soul gave way to disco, while DJ Kool Herc gave birth to hip hop in the Bronx. The glam rock of the New York Dolls and Alice Cooper split into glam metal and punk. Hippies and rednecks made peace in Austin thanks to Willie Nelson, while outlaw country, country rock, and Southern rock each pointed toward modern country. The Allman Brothers, Grateful Dead, and the Band played the largest rock concert to date at Watkins Glen.

Led Zep's Houses of the Holy reflected the rise of funk and reggae. The singer songwriter movement led by Bob Dylan, Neil Young, and Joni Mitchell flourished at the Troubadour and Max's Kansas City, where Bruce Springsteen and Bob Marley shared bill. Elvis Presley's Aloha from Hawaii via Satellite was NBC's top-rated special of the year, while Elton John's albums dominated the number one spot for two and a half months.
