"The album will be quite different from 'Guitartalk' since it will feature songs with vocals. The mix will be 50/50. Marcel found some great guest singers. The album will also be recorded with real drums, three guest drummers will be featured on the album."In related news, former SUN CAGED vocalist Andre Vuurboom is currently busy with his new project/band called SPHERE OF SOULS.
