ESSAM is Imarhans fourth album, recorded with the same core lineup, but marks a significant shift in their sound and approach.
Musically, it marks a departure from the rocky, bluesy, psychedelic Tuareg guitar-driven sound influenced by Tinariwens heritage moving toward something more open, modern, and exploratory.

For the first time, their long-time sound engineer Maxime Kosinetz stepped in as producer.
He travelled to Tamanrasset with Emile Papandreou (of the French duo UTO), a multi-instrumentalist who introduced electronic elements by sampling live instruments and reprocessing them in real time with a modular synthesizer subtly reshaping the band's sonic identity.
