Jeff Wayne's War of The Worlds has been a favourite album since I first heard it.
In particular is this song that summed up my teenage angst years. I had them but most of it was in my head and I didn't go through any sort of rebellious period. (Hindsight is a wonderful thing and I can see now how many times "Doing what I thought was expected of me" or "avoiding potential embarrassment" stayed my hand and caused me to miss out on what I know would have been wonderful times - even for a little while).
This is the third of my Desert Island discs.
