Arguably the most important record in modern music history. When Rock Island Line was released in the UK in 1955, it caused a sensation and influenced a whole generation of kids to pick up guitars and form bands.
Without this record there would have been no Beatles, Stones, Who, Led Zeppelin, Cream, Bowie and many others.
An interesting documentary about this is on YouTube
