In 2013, Norwegian prog rockers Airbag released their critically acclaimed third album ‘The Greatest Show On Earth’. Naturally, in some quarters of proggy fandom, people got excited. In some ways they were right enough to do so, since the album contained some fine music; it was all very well played and excellently produced. In other ways, it was hard to understand the hype. For all of Airbag’s obvious talents, the music all too often sounded as if it had been plagiarised from ‘Dark Side of the Moon’, ‘Wish You Were Here’ and ‘The Division Bell’. There came a point – fairly quickly, too – where you could legitimately ask why you’d spend quality listening time with music derived from such classics in a very obvious way, when you could put on a Floyd disc and hear it all done properly?
