I was 11 years old when the first Led Zeppelin album was released, the perfect age for a young kid to become entranced by a new rock and roll band. My older teenage brother bought the album and listened to it over and over again...and boy did I listen too! Our parents hated it of course, which made it all the more exciting! I loved all the songs on that album, but this one definitely shook me... The albums they made after that were all great, but the first one will always be very special to me, so that one gets my vote.
