The sound of Platypus's music can be described as guitar- and keyboard-driven modern progressive rock mixed with influences from the 70s rock and progressive rock scenes, employing vocal harmonies and lengthy instrumental pieces.
Their first album, When Pus Comes To Shove, did reasonably well, so much that it inspired a follow-up named Ice Cycles, released in 2000. After this the band parted ways and there are currently no plans to re-form to record another album. The legacy of Platypus does live on, though, in The Jelly Jam — a project formed in 2000 consisting of three-quarters of Platypus (Myung, Morgenstein and Tabor). They have currently released three albums.
