In June 2007, Darren was invited to be a member of brand new Irish group, The High Kings, along with Brian Dunphy, Finbarr Clancy, and Martin Furey. Their debut album was produced by David Downes (Riverdance, Celtic Woman) and the live concert DVD, recorded over 2 nights at Ardmore Studios Dublin, was directed by Declan Lowney (Celtic Woman) and produced by Ned O Hanlon (U2). Both were released in the US on the EMI MANHATTAN record label on February 28th 2008. Within 3 weeks of release, the album broke into the Billboard Top 200 at No. 154, and went to No. 2 on both the Billboard World Chart, and Billboard’s Heatseekers, as the week’s highest gainer!

They were signed to Universal Ireland towards the end of 2009 and released their second album, Memory, Lane in February 2010. After a successful sell out Irish tour the album went platinum in June, just 4 months after release. Memory Lane was released in America March 2011. The Live in Ireland album was recorded during the 2010 tour and released early 2011.

In 2013, the High Kings were signed to Sony Worldwide and their new album 'Friends For Life' featuring 8 original songs written by the band, is released in 22 countries around the world from Sept/October 2013, with the Canadian and US release in January 2014.
