Portico Quartet are a band from London. Their sound is made partially distinctive by the use of the Hang, a 21st-century percussion instrument. The group is composed of Jack Wyllie (soprano and tenor saxophone), Duncan Bellamy (drums), Milo Fitzpatrick (double bass), and Keir Vine (Hang and percussion). Nick Mulvey, former Hang player and percussionist, left in early 2011 to pursue his career as singer-songwriter. He is replaced by Keir Vine.
