In December 2015, David Gilmour performed a live recording of "Comfortably Numb" at Allianz Parque in São Paulo, Brazil. This performance was part of his "Rattle That Lock" tour, which supported his fourth solo studio album of the same name, released in September 2015. Gilmour’s tour marked his first return to South America since his time with Pink Floyd, and he expressed excitement about performing in venues that could hold up to 50,000 attendees. This concert highlighted Gilmour's enduring appeal as a live artist and showcased his iconic guitar work, further solidifying his legacy in rock music. The album "Rattle That Lock" received positive reviews, and the live performances from this era were significant in demonstrating Gilmour's ability to captivate large audiences with both new material and classic Pink Floyd hits.
