In 1951 the record "Rocket 88" by Jackie Bronston and His Delta Kings was released. This album went down in history as the first Rock and Roll album. To celebrate 50 years of Rock and Roll the Los Angeles Petersen Car Museum will display 40 cars and 75 guitars from Rock and Roll hero's. A limousine from Madonna, the Porsche from Janis Joplin and of course a Cadillac from Elvis. Guitars on display are from artists like Rod Stewart, Eric Clapton and Elton John.
