Passage: Pattinson plays the guitar and piano, and composes his own music. He appears as the singer of two songs on the Twilight soundtrack: "Never Think", which he co-wrote with Sam Bradley, and "Let Me Sign", which was written by Marcus Foster and Bobby Long. Pattinson also played the guitar on the Death Grips song "Birds", which was released in November 2013 on their album Government Plates.The songs were included in the film after director Catherine Hardwicke added Pattinson's recordings into an early cut without his knowledge, and he agreed that "one of them specifically, it really made the scene better. It was like it was supposed to be there." The soundtrack for the film How to Be features three original songs performed by Pattinson and written by composer Joe Hastings. Pattinson has said, "I've never really recorded anything – I just played in pubs and stuff", and when asked about a professional music career, he said, "Music is my back-up plan if acting fails." In 2010, Pattinson was awarded the "Hollywood's Most Influential Top Unexpected Musicians" award.In March 2017 interview Pattinson confirmed about contributing to the music of his upcoming film Damsel. Talking about it, he said that "I don’t play that much any more, though I am doing music for [‘Damsel’]. I used to differentiate between music and acting but the more I don’t play music, the more I push that area of my brain into acting. I improvise like I would when I play music."In February 2019, Pattinson collaborated with the Nottingham band Tindersticks and released a new single "Willow" for High Life original soundtrack.
