The same year, Wehrkamp was involved in a project called Sounds like Christmas, that featured artists such as John Wetton (King Crimson), Steve Walsh (Kansas), and Trent Gardner (Magellan).
The joke was on me then... it was one of the best solos I had ever heard; a combination of playfulness (Steve Vai), virtuosity (Edward van Halen) and speed (Yngwie Malmsteen) and still with a completely recognizable own sound.
It goes without saying that I worked with Gary again on the Star One album 'Space Metal', especially because he had to play a duel with the fastest keyboard player of the world Jens Johansson (the outcome is undecided).
In 2002, Wehrkamp was a guest guitarist on Explorers Club's second release Raising the Mammoth, which also included prog artists John Myung (Dream Theater), Marty Friedman (Megadeth), and Terry Bozzio.
