I'm in the midst of writing an epic progressive rock song (think early Rush epics) but I'm having some trouble with lyric ideas. Any suggestions on topics I could write about? I have the acoustic intro written (D major, 1-4-1-5 chord progression, slowly building up, repeating and every once in awhile ending on 2 instead of 5) and it seems to have a very "Fountain of Lamneth" sort of feel to it. Suggestions please, I'm really stumped on this one. Thanks!
