Dunnery continued to write songs as and when the inspiration took him. He has sometime commented that his songwriting is a periodic activity, stating in a 2009 interview with the PhillyBurbs online newspaper: "I cannot write songs on a nine-to-five basis. At the risk of sounding pretentious, my songs come from somewhere else and I have to wait for them, so it's not up to me when I receive them. When the songs start to come, they all come at the same time. I may get 20 songs in three to four days and then it all stops again."
Dunnery would join singer Steve Nardelli's revived 1960s progressive rock/beat band The Syn as guitarist, playing alongside Nardelli, keyboard player Tom Brislin and bass player Jamie Bishop as well as two members of American progressive rock band Echolyn (guitarist Brett Kull and drummer Paul Ramsey). Dunnery also brought in his backing vocal foil Dorie Jackson. He was musical director for the band's 2009 album Big Sky. This line-up of The Syn began an American tour in April 2009 but broke up after six dates.
Dunnery's next album, There's a Whole New World Out There, released on 3 October 2009, was centred on the New Progressives (plus guests) and featured a succession of reworking of old It Bites songs, plus a variety of similarly rearranged cover versions. The New Progressives toured the UK, American and Australia to promote the record, with guest appearances from other musicians where possible.
In 2009, Jem Godfrey (Frost*) announced on the Frost* Forum that he and Dunnery had both contributed solos to the title track of Big Big Train's upcoming album, The Underfall Yard.
