A Pennsylvanian by birth, Keith Kenniff is an honors graduate of Boston’s esteemed Berklee College of Music, best known as the brains behind dulcet ambient/electronic practitioner Helios and the fingers on the ivories of post-classical piano minimalist music as Goldmund (the latter’s music once described by no less an authority than Ryuichi Sakamoto as “…so, so, so beautiful…”). Together with his wife Hollie, Keith also records as Mint Julep, and the two released their debut album “Save Your Season” which NME coined as “Unquestionably Beautiful”. A succession of albums under those aliases has made Kenniff the darling of discerning critics and his music has been widely used in film, tv and advertising, for clients such as Apple, Facebook, Google, Paramount, MTV and Warner Brothers.

Lovely to meet you,
let me know what you have in mind.
