A band's fan-funded debut album has shot to number 12 in the charts - outselling established artists including Daft Punk and Justin Timberlake in the process.
Despite not having the support of a major record label, Hey! Hello!'s self-titled record - funded entirely by the crowd-sourcing website Pledge Music - is currently number 12 in the midweek charts.
The Anglo-American duo behind Hey! Hello!, New York singer Victoria Liedtke and British artist Ginger Wildheart, said it was "amazing" the way the album had been embraced.
Editor-in-chief of Classic Rock Scott Rowley said there was a great irony that the "great record" had been produced by someone who had been discounted as a "lost cause" and "too old" by major record labels.
The growing appeal of the band, who have been described as a cross between ABBA and Green Day, has enabled them to tour the US and Japan, and shoot a video for a new song.
