In July 2016, David Gilmour performed "Fat Old Sun" at the Roman Amphitheatre in Pompeii, a venue historically significant for its association with artistic expression, previously hosting the legendary Pink Floyd's "Live at Pompeii" film in 1972. This performance was part of a tour promoting his fourth solo album, "Rattle That Lock," released in September 2015. The album marked a significant point in Gilmour’s career, showcasing his continued evolution as a solo artist following the dissolution of Pink Floyd. The 2016 live performance not only celebrated his solo work but also paid homage to the iconic past of the location, blending nostalgia with Gilmour's signature guitar artistry. Notably, he became known for his atmospheric sound, and this live rendition exemplifies his ability to captivate audiences with extended improvisations and emotive delivery, further solidifying his legacy in rock music.
