With his debut album Goon out today on True Panther, Tobias Jesso Jr. put on his most intense piano faces for Conan O’Brien. He chose to perform “Without You,” and the Canadian songwriter employed a full string section for the occasion.

Jesso also brought along some noteworthy friends for the performance: Danielle Haim is there on drums, and super-producer Ariel Rechtshaid joins in on guitar. Stream above and give Goon a go.
