This is a complex song, that the band makes sound simple. Its "Bohemian Rhapsody", from the 1975 album (not CD, lol) "A Night at the Opera". It starts as a ballad, then goes into opera, then hard rock, with an intro, guitar solo, and an "outro" in the mix. It was another very different sound at the time, which I think added to its success. Freddie Mercury has a voice that could be an instrument by itself if you ask me. This is one of those songs/bands that will last forever. Like Led Zep, Aerosmith, The Beatles, The Rolling Stones, etc., its timeless.
