René Merkelbach - keyboard

Arjen explains:

René works in the RS29 studio where I recorded/mixed most of my CDs, and has played keyboard for a lot of different types of bands; from the symphonic Rubicon to the deathmetal band Gorefest. Rene has fast fingers and is a very versatile keyboardist. The only thing that gets on my nerves is that his guitar imitations on the keyboard are just too damn close to the real thing!
