The Herbaliser are all about moving forwards, onwards and upwards. Bonding over a shared love of jazz, funk, rare groove and hip-hop in the early 1990s, West London duo Jake Wherry and Ollie Teeba have evolved with each chapter in their 15-year story. First it was instrumental beats, breaks and samples. Then they added guest rappers and vocalists. Later, as international festival favourites, their line-up swelled into a mini-orchestra with lush arrangements to match.
