Nimrodel was an Elf-Maid an aquaintance of Amroth. Another reference is that it refers to multiple characters. From Tolkien.
I can not believe that Andy Latimer (vocals, guitar) thought his singing voice was not good enough and wanted to get a different vocalist in the band. They auditioned many vocalists and came to the conclusion that Andy's vocals were superior. He has a beautiful and unique singing voice imo. He is also one of the greatest guitarists to this day.
It's actually quite refreshing to have someone who reacts while having informed opinion about the whole genre and all, a very good track from Camel, perhaps not their best but still really enjoyable!
Yes, Camel has that smooth and "easy-listening" style that makes them as a good introduction to the 70s Progressive Rock.
Thanks for your proactive reactions, hope we're gone for a long ride!
