Take pomp-rock, shorten its sights (unpump the pomp a bit), inject a bit of youth, alternate male and female vocals and what have you got? The Invaders (from West Yorkshire — not to be confused with two American bands of the same name), who still manage to have all the snap and appeal of week-old pastry. Too much of their “Rock Methodology” and not enough playfulness makes the Invaders a dull band.
