Many of my friends feel that Genesis is not an easy band to listen to. They are completely right, you really have to have an emotional connection to them to withstand the scattered and maniacal perfection of their music. For me it lies in the album Selling England by the Pound (1973) and the song In The Cage off the double album, The Lamb Lies Down on Broadway (1974). The song is about a man who falls asleep, a sleep so deep he's close to death. In this dream he is in a cage of stalactites and stalagmites. He calls for help from his dead brother who is beyond the cage. His brother wont help him as he is in a different world, finally he scatters himself into a million different pieces and flies from the cage and is dead. He can now join his brother. Well thats my interpretation. See what you think
