Showing no trace of creative fatigue, O'Rourke is joined in Kan by Brian Finnegan, a founding member of one of Britain's most important ever traditional band's Flook. Finnegan and O'Rourke's Irish and Scottish musical roots are deeply woven into the new music which makes "Sleeper" such a potent debut, but their artistry and skilled writing are only half of a homogenous quartet which is made up of lead instruments and also features the incredible musicality and compelling talents of Ian Stephenson and Jim Goodwin.
