Mumford & Sons released their second album, Babel, in September.  The song debuted at No. 1 on the Billboard 200 chart and has sold over 2 million copies.  It also won the Grammy Award for Album of the Year.

But, the band apparently does not care.

Front-man Marcus Mumford says the band is focused on live concerts and not so much on record sales.  Mumford explains:

"We've asked our manager just not to keep us up to date on records [sales]. We know about ticket sales pretty well, because that's what we sort of know and love, record sales aren't really that relevant to us."

Mumford & Sons is spending the majority of the summer on the road.  They are headling several festivals including Bonnaroo and Lollapalooza.  Many of their shows have already sold out.
