"Is There Anybody Out There?" is a song from the eleventh Pink Floyd album, The Wall. It is largely an instrumental, containing few lyrics and mainly consists of a classical guitar solo. David Gilmour has said that he tried to perform it and was not satisfied with the result ("I could play it with a leather pick but couldn't play it properly fingerstyle"). Accordingly, session musician Joe DiBlasi was brought in to record the album part. This version, played with cello and guitar, was arranged and recorded by Quartus and Lara in October 2025 in their Stanford studio.
