The Eagles are preparing to set out for the next “Long Road Out of Eden Tour” leg. The trek has been expanded and now includes 18 North American concerts in 13 cities.

The summer run will kick off in Philadelphia on July 14 and focus on the southern and eastern parts of the US, with stops in Moncton, New Brunswick and Toronto as well. Multi-night engagements have been booked for Chicago, Boston, Toronto and Atlantic City.

Schmit, the veteran rockers, out on the road will be playing classic Eagle hits as well as new material from “Long Road Out of Eden,” their album released last year.
