From blabbermouth.net:

DREAM THEATER vocalist James LaBrie will record a guest appearance on one track on the upcoming solo album from drummer John Macaluso (TNT, ARK, YNGWIE MALMSTEEN, JAMES LABRIE, STARBREAKER), entitled "John Macaluso's Union Radio - The Radio Waves Goodbye". The CD, which is tentatively scheduled for release in November via Lion Music, is described in online post as "a continuation of the ideas and themes John was working on while with ARK. The last ARK CD was to be called 'A Radio Kaos', which was canned after the band broke up." Other guest musicians set to appear on the album include Marco Sfogli (guitar), Randy Coven (bass) and Vitalij Kuprij (keyboards). More information will be made available soon.
