Former Dream Theater Musicians Unite

Florian Zepf, guitarist and the driving force behind The Progressive Souls Collective has gathered international prog musicians Aquiles Priester (ex-Angra & Tony MacAlpine) on drums, Conner Green (Haken) on bass, Kevin Moore (ex-Dream Theater, O.S.I., Chroma Key) creating loops and programming, Vladimir Lalic (Organized Chaos) aptly handling all vocals and Luis Conte (Phil Collins) on percussion to come together on the album Sonic Berth.

As a very special guest keyboard maestro Derek Sherinian (Sons of Apollo, ex-Dream Theater, and many more) recorded all keyboard parts on the album, giving the songs a very special touch of virtuosity, sound design and of course character. Metal Express Radio’s Bryce Van Patten caught up with Florian to talk about the new release, what it was like working with Ex Dream Theater members and what the future has in store for The Progressive Souls Collective.
