Swan Song was a single from the band Led Zeppelin but also morphed into a project called Swan Song Records. This was a record label launched by the band in 1974, using the same Icarus logo. It is said they use this fallen Greek God as a symbol of reminder to not become hubris and overconfident no matter how big they get.
Led Zeppelin is a world-famous rock-n-roll band from the UK. They started becoming popular during the 1969 movement of psychedelic rock music, which brought them down the path of creating more political songs. The lead singer also brought a lot of mythology and mysticism into their lyrics. They are most known for their songs "Dazed and Confused", "Stairway to Heaven" and "Immigrant Song". Even though their style was viewed as more folk and bluegrass, they are still seen as one of the most influential rock bands to ever exist.
