This week, I had the opportunity to see a unique musical act in Mannheim, Germany. Specifically, the one-man show put together by up-and-coming jazz phenom, Jacob Collier. Jacob Collier, for those that don’t know, gained notoriety through his creation of multi-part YouTube videos for which he not only composes original and creative arrangements of classic songs, but also plays every instrument in the mix. His style is characterised by extensive use of vocal layering/a cappella arrangements, versatile and extensive re-harmonisations, polyrhythms and metric modulations, all rooted in jazz/funk style inspired by the hit composers of previous decades (Stevie Wonder, Herbie Hancock, Michael Jackson, the Beatles, etc.).
