Promotion and release
The song's involvement with Tales of Xillia was first announced in May 2011. As the theme song, the song played an integral part of advertising for the game, and played during the opening sequence for the game. Hamasaki performed the song on her Power of Music 2011 A tour, held from May to October 2011. At the 62nd NHK Kōhaku Uta Gassen held on December 31, 2011, Hamasaki attended, performing "Progress" live. She performed the song also during her COUNTDOWN LIVE 2014 - 2015 A Cirque de Minuit, and her ARENA TOUR 2015 A Cirque de Minuit.
Music video
A music video was produced for the song, directed by Masashi Muto. It features Hamasaki performing the song in profile against a white background, interspersed with sped up footage of a journey through a city. The camera travels through streets, subway stations and hallways, occasionally slowing to focus on a bystander. While the scenes begin in Tokyo, mid way the view changes to the Japanese countryside, followed by American beach and desert footage. The final bystander the camera view stops at is Hamasaki herself.
Critical reception
Critics were very positive about the song's arrangement. CDJournal praised the song's "dramatic arrangement", noting the "solemn strings intro" which leads into the song's introduction backed by piano and next into a "hard, serious sound" centred on the guitar. Embrace Your Magazine reviewer Kai and Anime Revolution felt similarly, with both reviews noting how well the song's dramatic qualities were suited to Tales of Xillia.
