The Sound Of The Underground Alternative Vocal Mix music video was created from the original 35mm films by editor and director Chris Fox.
“You never know what you might find when you dig into the raw footage from a music video and we were amazed to find that director Phil Griffin had recorded each of the girls singing every line of the song… In total, the band recorded about four hours of footage and there were so many beautiful moments to squeeze into the video. I wanted to give each section of the shoot its moment to shine: the performance, the slow motion, the glitter drop. There are fewer fast-paced cuts so we can soak up every moment and bask in the glory of Girls Aloud. The film negatives were rescanned in true 4K – giving fans a crystal-clear look into the past – and the final edit was colour graded to closely match the original music video.” – Chris Fox (2023)
