Electrafixion. The band toured extensively and released one album,
Burned, in 1995. After a few
singles and more touring, the band began to play a large number of old Echo & the Bunnymen songs at their shows. In 1996, the Bunnymen reformed. Sergeant also returned to solo work in 1997, under the moniker Glide, producing experimental,
ambient and psychedelic instrumental music based around keyboard and electronic sounds. That year, he released the live
Space Age Freak Out, followed by another live album,
Performance, in 2000. Glide began to tour, and would often open for Echo & the Bunnymen in the early 2000s. Glide released

Echo & the Bunnymen, formed "Poltergeist" with former Black Velvets drummer Nick Kilroe. They have been playing live and released an album called
Your Mind Is A Box (Let Us Fill It With Wonder) in June 2013. Sergeant told journalist Jon Cronshaw that: "We don't want to have to stick to the verse-chorus-verse format, because that's what we have to do in the Bunnymen. We're trying to do something that's a bit different, and a bit more open-ended. We can do anything with this project because we're not governed by any preconceptions about what people expect. If we wanted, we could do a 40-minute ambient nose flute solo if we really wanted, you know? I just like that aspect that we can take it anywhere." In 2021, he published
Bunnyman, the first part of his autobiography covering his childhood and the formation of Echo and the Bunnymen up until just before they replaced the drum machine with Pete de Freitas. The second part,
Echoes was published in 2023. ==Personal life==
