At the 2008 North Sea Jazz Festival that was held in The Netherlands this past weekend, Dutch trumpet player Rik Mol spoke briefly in an interview about the news that he is going to record some music with Jamiroquai. He said that he is going to record his second album with "the guys." Rik said that he is happy about the opportunity to work with the band - he met them whilst performing in London and loves the feeling of rhythm in their music.
UPDATE (15 July 2008): I have been told that Rik Mol will be doing some work with Rob (Harris), Derrick (McKenzie) and Paul (Turner) - and not recording with Jamiroquai. This work (as with other 'side projects' that the bandmembers are involved with) will be done when the band are not working on the new Jamiroquai album, which currently takes priority.
