Jos Rivers is one of the UK’s most exciting emerging artists, with a journey shaped by four years of careful nurturing by AuthorityMGMT together with Pieces of 8 Music.

Signed to RCA Records straight from school, we developed Jos’ distinctive artistic identity, combining her trademark honesty with an impressive vocal range and relatable songwriting.

Her debut EP, Thankyou So Very Much, has now surpassed one million streams — a significant milestone for a new artist.

Alongside a major record deal, we brought onboard live agency WME, strong financial and legal teams and built a superb live band around her.

With these foundations firmly in place, Jos continues her journey towards future stardom.

Jos was managed by AuthorityMGMT from 2022 - 2026.
