'Hidden Waters: Strange and Sublime Sounds of Rio de Janeiro' is compiled by Joe Osborne (founder of specialist Brazilian music platform Brazilian Wax) and Russ Slater (editor at large of Sounds and Colours). Focusing solely on the 'Rio Scene', rather than taking on the mammoth task of tackling Brazil as a whole, this collection presents 20-plus ground-breaking artists selected from Rio's resurgent music scene. By presenting a snapshot into the pulse of the city and the vibrant musicians that live in it, 'Hidden Waters' collates tracks from a wide spectrum of musical genres from the avant-garde edge to bossa nova, samba, Candomblé, lo-fi rock, jazz and funk.
