I know Erol Alkan primarily for his DJing-- His 2005 Essential Mix for Radio 1 gave me so much; bittorrent it. Alkan started the London clubnight Trash, which went on for 10 years, and he won Mixmag's DJ of the Year for 2006. He's also got massive Superstar DJ association: the Soulwax documentary features him, and when I saw him spin it was at the Fixed party at WMC last year, with Simian Mobile Disco.
He's involved in other projects besides remixing, though. Check this. He produced the Late of the Pier album Fantasy Black Channel, just released in the States last week, as well as the Long Blondes' album Couples and the Mystery Jets' Twenty One. He's even got his own music-with-guitars-in-it project, a psych outfit called Beyond the Wizard's Sleeve.
