In June of 2006 Matt Scannell announced that the band was working on a new album. The official website also announced that Neil Peart (Rush) drums on three tracks on the new Vertical Horizon album, which will be done after the summer 2006. One of the songs is a collaboration between Neil and Matt Scannell of Vertical Horizon. <-- This is from Wikipedia. So, the low down is Neil will be on the upcoming release from VH.
Neil does NOT drum on the vertical Horizon CD 'Go'. neil is friends with Matt from VH and they are working on a release later in 2007. I hear it is a Matt Scannell solo album separate from his vertical horizon stuff...can't wait!
