To call Babelsberg a 'solo album' would be a misnomer. While it was written and performed by Gruff Rhys, the Super Furry Animals frontman roped in long-time musical cohorts, drummer Kliph Scurlock (formerly of The Flaming Lips), as well as multi-instrumentalists Stephen Black and Osian Gwynedd.

The collaboration doesn't end there. Rhys sat on these 10 songs for 18 months, waiting for Swansea-based composer Stephen McNeff to pen orchestral scores for each track, which were then played by the 72 members of the BBC National Orchestra of Wales.

The result is a gorgeous, sumptuous affair that comes across like Richard Hawley fronting the Count Basie Orchestra, or Jarvis Cocker jamming with Cole Porter.

Lead single Frontier Man is as catchy as a cold in a creche, Rhys doing his best Welsh Scott Walker impression, on a musical hike through the California desert. The swirling psychedelia of Limited Edition Hearts comes complete with a spiralling falsetto chorus that's impossible to hear without humming along to.

Oh Dear is frenetic, galloping pop with a decidedly '60s feel: think Austin Powers without the irony. The Club, meanwhile, soars in on sweeping strings, as the Welsh indie king tries his tonsils out as a crooner, narrating a tale of being ejected from a nightclub with all the dramatic flourish of War & Peace:

"They threw me out of the club/ The club that I built with my own two hands/ They threw me into the street/ Into the street where the gangs hang".

Named after a town he encountered on a 2014 tour and evoking the biblical Tower of Babel, Babelsberg is one of the finest albums Rhys has ever produced, with or without the rest of the band.
