1. A vane assembly adapted for a gas turbine engine, the vane assembly comprising
a first vane segment that extends circumferentially about an axis, and
a second vane segment having a band that extends circumferentially about the axis and a plurality of vanes coupled to the band and extending radially from the band,
wherein the first vane segment is coupled to the second vane segment, at least a portion of a radially-outward surface of the band of the second vane segment in contact with at least a portion of a radially-inward surface of the first vane segment at an axially aft most portion of the first vane segment and an axially forward most portion of the second vane segment to mate the first vane segment with the second vane segment and to place the plurality of vanes of the second vane segment in a position to lie between an axially-forward surface of the first vane segment and an axially-aft surface of the band of the second vane segment so that the first vane segment and the second vane segment are damped.
