Ed Warby was born and raised in Rotterdam and is best known as the drummer for Gorefest and Ayreon. He also appeared in the band Agressor in 1982 and joined the Eindhoven-based prog-outfit Elegy in 1987. Moved to Gorefest in 1992, where he replaced the former drummer just before the recording sessions of "False", he had to learn all themes and develop his work in just two weeks, which he managed to achieve in a matter so fast that producer Colin Richardson nicknamed him Fast Eddy.
After Gorefest split up in 1999, he took part in the re-united Gorefest in 2004. In 1998, Arjen Anthony Lucassen asked him to perform on his album Into the Electric Castle, because Arjen was impressed with Warby's works with Gorefest. From that moment on, Ed Warby had performed on Ayreon's every album, except for Universal Migrator Part 1: The Dream Sequencer. He also performed on the re-recording of Actual Fantasy (the original recording featured a computerized set of drums). He's also a member, since its creation in 2002, of Lucassen's band Star One.He helped the Dutch popband Krezip during the recordings of "Days Like This" in 2002. He also helped German band Love Like Blood with three songs of their album "Snakekiller", in 1998. In 2005 he played live with the Dutch Gothic metal band After Forever.
In 2008, Warby began a doom metal project named The 11th Hour, and released the album The Burden of Grief in 2009. All guitars, bass, drums, keyboards, and clean vocals are performed by Warby, with the additional growls contributed by Rogga Johansson (Ribspreader).
