Schlitt and Hartman, after arranging worship music together for a youth retreat, reunited for an independently released praise-and-worship CD in 2007, calling themselves II Guys from Petra and titling their album "Vertical Expressions". The songs featured contemporary praise songs in a raw-sounding, electric rock format, and included two bonus tracks from Petra's recorded farewell performance that had not been included on the "Farewell" CD. Studio musicians played drums and bass, and former Petra keyboardist Jim Cooper teamed with Hartman on production. Hartman and Schlitt have since performed several shows together, playing acoustic renditions of Petra and II Guys songs as recently as early 2010.
