"Elysium (I Go Crazy)" (sometimes called Elysium) is the 5th single by Liverpool dance trio Ultrabeat. It was released in 2006 and played throughout the summer of that year. Ultrabeat used the vocals of Rebecca Rudd to Scott Brown's hardcore cult hit "Elysium" and gave it a trance remix, achieving further commercial success for a song which is perceived by many hardcore fans as a great dance anthem.
