On 11 May 2009 the Jamiroquai Live at Montreux 2003 concert will be released on high definition Blu-Ray. From the credits of the original DVD release in 2007 it was noted that the concert was filmed in high definition and its great the the people at Eagle Vision have been able to release the concert in HD.
I don't have details of exactly which countries it will be released in although links have been spotted on French (Alapage.com - 12 May) and English (SofaCinema.co.uk - 11 May) sites.
