(Prog) Rick Wakeman and Billy Sherwood will appear on Leon Alvarado's album The Future Left Behind. The concept album is due out on July 30 and is a follow-up to 2014's Music From An Expanded Universe.

Yes bassist Sherwood appears on guitar duties and also helped the composer record the album, while Wakeman performed on the track Launch Overture. The record was mastered by longtime Pink Floyd engineer Andy Jackson.

Alvarado says he was inspired by Wakeman's iconic work Journey To The Centre Of The Earth, as well as music by Vangelis and Yes. He says: "My goal was to create something that would combine the artwork and the music into one cohesive vision. I thought that basing my project on a sci-fi story would be very fitting and would give me the necessary creative space to make music that entices the imagination." Read more here.
