Allan Hardenberg and David Lewis have been active in the Dutch dance scene since its very beginning. In 1997, the two entrepreneurs organized events such as Armin Only, Tiësto Solo and "Three DJs in a Boat". Seven years after they started their collaboration, Hardenberg and Lewis decided to start their own independent event agency and founded ALDA Events. It originated in 2007 and has since then been operating from Amsterdam. Early years were Armin Only, Best Of Both Worlds and A Day at the Park. Eventually, the event portfolio would extend with events like Electronic Family, Citymoves, various Armada concepts and other event nights during Amsterdam Dance Event (ADE). The past years ALDA creates new concepts like Amsterdam Music Festival and The Flying Dutch.
In 2011 and 2013 ALDA Events was nominated for the International Dance Music Awards (IDMA) in the category Best Event Promoter Worldwide. Besides that, the A State of Trance concept has won various awards throughout the years.
