The dates begin August 2 in Baltimore and wrap August 19 in Westbury, N.Y. The “collaborative tour” itinerary includes shows in Charlotte, Philadelphia, Boston, Chicago, and a performance at New York’s Rumsey Playfield.

The members of Nickel Creek and Apple met several years ago in Los Angeles and began occasionally working together at the club Largo – an intimate and magnetic music night spot well known for stellar lineups and surprise appearances.

A loose and friendly musical exchange began with Apple sitting in on Sean and Sara Watkins’ “Watkins Family Hour.”

Nickel Creek’s mandolin player, Chris Thile, of the Watkins returned the favor, playing with Apple whenever possible.

For the August dates, fans will be treated to an expansion of those collaborations. Material will be pulled from both artists’ solo catalogues, but audiences can expect to hear anything from pop standards to country classics to modern rock covers.

Apple’s presentation will be unique; she will rely on Nickel Creek for back-up during her set.
