Mark Ellis, a.k.a. Flood, is an engineer and producer nonpareil. Following acclaimed stints at Some Bizarre (Cabaret Voltaire, Marc Almond) and Mute (Nick Cave), his big break came from engineering U2's The Joshua Tree for super-producers Daniel Lanois and Brian Eno. By the time of '93's Zooropa, he was sharing production honours with Eno. He's since attracted the biggest names in rock, including The Killers and PJ Harvey.
