Robyn appeared on four episodes of this syndicated show. From Wikipedia:
Acoustic Café is an independent, syndicated radio program, produced in Ann Arbor, Michigan, United States. (Not to be confused with the Japanese instrumental group of the same name founded by Norihiro Tsuru.) Started in 1995, Acoustic Café presents singer-songwriters in various genres, playing songs in the Acoustic Café studio and chatting with host Rob Reinhart. A selection of current and past recorded material (on CDs) is also a part of each weekly program.

Robyn also had a studio track featured on Episode 75 of Acoustic Cafe, but since that was not a live performance, it's not listed in our database of gigs.
