According to Pitchfork, Imogen Heap said of the reunion, "We never really got to tour as Frou Frou that much but we are making up for it and opening every show on this world tour we are on with this song."
Sigsworth added, ""Guitar Song": It’s a song—with guitar! Easy, breezy and summery. Like João Gilberto playing shoegazer music. Or something."
