A multitude of genres are carefully cross-stitched by these pseudonymous musicians, from New Orleans marching bands to Coventry ska ones, art-rock to classical. Shifting, overlaid time-signatures and rhythms click into intricate place without feeing constrained. Emotions are equally contrapuntal. The woodwind-led introduction to ‘Draining Refrains’ is surgingly optimistic chamber-pop, but the lyric describes recurring depression. Saxes supportively cradle the subject of ‘Lunch for the Worms’ while pondering an eco-funeral, as tubas give melancholy weight then comic emphasis to ‘Mystery Meat’. The Cubist painting on the cover is about right. From a (barely) pop perspective, it's nice to hear some rhythmic imagination, and from a (barely) jazz one, the melodies and lyrical themes make a pleasant change. Perhaps Contraption are keen, award-winning street-giggers, and this agreeably eccentric, whimsical affair should connect, and sometimes irritate, at festivals.
