"Hollow" is a song by American rock band Alice in Chains and the first single from their fifth studio album, The Devil Put Dinosaurs Here, released on May 28, 2013.

[3][4] "Hollow" reached number one on Billboard's Mainstream Rock Tracks (their fourth song to do so) [5] and stayed on the chart for 20 weeks.

Asked by Music Radar if he worked out the phrasing over time or if it was immediate, Jerry Cantrell said of the riff: "That one was pretty immediate.

[10] The video depicts the daily routine of an astronaut (played by Ian Mackay) orbiting around earth whilst performing various floral experiments on the ship.

He is shown often chatting to his significant other (played by Eli Jane) on Earth via video calling.

As the video progresses, and his tenure in orbit turns from months into years, the astronaut slowly but steadily tires of his mundane routine, leading to emotional conflict with his significant other and suffering a mental breakdown.

Near the end of the video, having completely lost his mind, and a visible tumor on his neck, the astronaut takes a flamethrower and destroys the experiments on board, which leads to the entire ship catching fire and crumbling with him inside.
