The Claypool Lennon Delirium is an American rock band, composed of bassist/vocalist Les Claypool, known for his work in Primus, guitarist/vocalist Sean Ono Lennon from The Ghost of a Saber Tooth Tiger, keyboardist/vocalist João Nogueira from Stone Giant, and drummer Paulo Baldi of Cake.
[1] The band was conceived in 2015, with Claypool knowing that Primus would take a year off after touring alongside The Ghost of a Saber Tooth Tiger and Dinosaur Jr.
He kept in touch with The Ghost of a Saber Tooth Tiger's lead singer Sean Ono Lennon, who had not planned any musical project for the following year.
Claypool invited Lennon to his guesthouse to drink wine, run some ideas, and play drums.
[6] The duo embarked on a brief headlining tour in support of the record in late 2018, with successive dates in the spring of 2019.
