During the tour that began in October 2010, starting from New York for promoting Dust Lane, Yann Tiersen and his band have begun to unravel this new material, and the first two pieces from Skyline, "The Trial" and "Another Shore", were subsequently performed live.

Skyline was subsequently mixed by music producer Ken Thomas at The Chairworks, a residential recording studio complex located in Morrison Street, Castleford, near Leeds, West Yorkshire, England, and mastered at Air Studios in London by mastering engineer Ray Staff, best known for his work with Led Zeppelin, The Rolling Stones, The Clash, Black Sabbath, and Muse.

It was about an hour of krautrock, electronic, and experimental music involving a dozen of synthesizers and analog keyboards with the first three pieces of the set list taken from Dust Lane and the remaining five from Skyline.

"[13] UK based popular music magazine Mojo in its review stated that "[e]xpectations are defied by a series of grand, eccentric chamber essays, and only a paucity of Tiersen's killer melodies disappoints.

"[11] Ken Scrudato in his review of the album for Los Angeles-based magazine Filter stated that "its tracks are beautiful storms for restless times" and that "every song [is] like a journey through a forest of emotions".
