My Morning Jacket have added a handful of dates to their already robust tour schedule. The Louisville, Ky. rockers will find themselves on the West Coast in September, and will now let fans give their input on what the live set lists will consist of.

My Morning Jacket will head to Seattle, Wash. on September 9, followed by Portland, Ore.; Boise, Idaho; three stints in Los Angeles, Calif. and a show in Berkeley, Calif. See all the new dates below. These dates are in addition to their already announced summer dates with Band of Horses.

The group has also introduced a 'Spontaneous Curation Series' concept for all live shows on this tour. My Morning Jacket will allow fans to affect each night's set list, beginning with their European dates later this month. They will use Twitter to execute the 'Spontaneous Curation Series' and pull from their entire catalog. MMJ issued the following statement about the series:

Curating spontaneously is best achieved by communication within a community because otherwise, curating in a vacuum can lead one to spontaneously combust. However, a spontaneously curated show is the best way to achieve collective musical combustion. Concurrently, we are crazed with excitement and curiosity to see how Roll Call and concert goers spontaneously contribute to our eclectic collective curation!

In related news, frontman Jim James will concentrate on his new solo album once My Morning Jacket wraps up their tour. The record will have some surprises in store for fans. "I’m really proud of it," James said. "I think it’s got some different soundscapes that I’ve been into that maybe have been hidden on some Jacket records.”
