The Idea of North is an Australian a cappella quartet, originally composed of Trish Delaney-Brown (Soprano), Megan Corson (Alto), Nick Begbie (Tenor), and Andrew Piper (Bass). They formed in 1993, while studying music at the Australian National University in Canberra, with their first album The Idea of North recorded in 1997. They followed this up with their second album The Sum of Us. When Megan left to move to Melbourne in 2002, they recruited Naomi Crellin to fill the slot. Read more on Last.fm
