Since 'Azora' in 2014, Tamu has dedicated his spare time to making music, whether his own or for other artists. He took a moment after his EPs Alba (2015) and Bala (2017) to produce Fenne Lily's earliest singles, which collectively reached over 70 million streams before, in 2019, releasing his own debut album Little Death Summer. Often starting his writing by composing a heavily layered instrumental, adding vocals afterwards and experimenting with space and production techniques from a range of genres from electro to hip-hop via pop and folk, he quickly became renowned for his "exquisitely layered excursions" (Stereogum). This continued into his experimental three part single 'Heaven, Holy, Heathen' (2020) and his production for emerging talent Wil Owen.

For his new album Late To My Funeral, Tamu decided to take himself out of his comfort zone by reversing his previous technique, instead writing the song on guitar first and then having fun with the production, adding things to compliment and embellish the original idea. "I feel like the best songs tend to work in a stripped back form – so starting from that point leaves you with something a bit more raw and vulnerable” he explains as his reasoning for this change.
