Not content with being the fastest-selling album in the UK so far in 2012, Mumford & Sons' Babel has now achieved the same feat in the US market.
According to Nielsen Soundscan, the British band's album sold in excess of 600,000 last week to claim their first ever No.1 on the Billboard 200.
It also marks the first ever No.1 on the chart for the band's US indie label, Glassnote Records.
Babel easily beats the first-week sales recorded by Justin Bieber's Believe (374,000) - 2012's previous fastest seller.
It marks the best week for a 'rock' album since AC/DC's Black Ice hit No. 1 with 784,000 sales on the Nov. 8, 2008 chart.
It was also the second largest digital sales week for an album in US history, with 420,000 downloads sold.
And Babel scored the second biggest sales week overall for an album in 2012. Adele's 21 remains top, with 730,000 units sold in the week following her Grammy wins earlier this year.
