It's been a while since Mumford & Sons released their groundbreaking debut LP Sigh No More (2009 to be exact), and the band has announced that the long awaited sophomore follow-up will be released in September (Note: A September 24th release date was confirmed by Dutch radio station 3FM). The news was announced by the band themselves during a performance at Pinkpop Music Festival in the Netherlands this past weekend, after which they recorded a live session with the previously mentioned 3FM radio station. During the session, the band discussed the forthcoming LP as well as performing a brand new track titled "Where Are You Now." The entire live session is available to watch after the jump.

In more Mumford & Sons related news, the band has announced that they will be conducting a series of mini festivals across the United States prior to the release of their sophomore LP. Titled Gentleman of the Road Stopovers, the mini festivals will take place in four cities, including Portland, ME, Bristol, VA, Dixon, IL, and Monterey, CA, and will see the band headlining with the help of St. Vincent, Gogol Bordello, Dawes, Grouplove, and more. Here is what the band had to say about their plan:

The Gentlemen of the Road Stopover is based loosely upon our favorite festivals like Colorado's Telluride Bluegrass and Scotland's Loopallu Festivals. We want to stop off in towns where bands don't usually tour, and celebrate the local people, food and music.

We're keen to promote the town's local businesses, and we'll be using the local bars and venues for after-show parties, whilst working closely with the local people to get everyone involved in making these shows spectacular. There will be a host of our friends playing too, and the vibe falls somewhere between 'travelling Victorian circus' and 'Victorian travelling circus'. It should be a whole lot of fun." 

Tickets for the Portland, ME, Bristol, VA and Monterey, CA events will go on sale starting this Friday, June 1st, at 10:00am local time, with the Dixon, IL stopover going on sale on June 9th at 10:00am CT. Early-bird tickets for the events will go for $59 and come in limited quantity on a first-come, first-serve basis, with general admission going for $69.
