This Sunday, the Edmonton Symphony is presenting a concert in its Sunday Showcase series that features not only a delightful program onstage (with music by Dvořák, Liszt, Arutunian, Estacio, and Falla) led by ESO Music Director Bill Eddins and resident conductor Lucas Waldin, but also a well-thought-through sequence of events in the lobby, before and after the concert.   Before the 2 p.m. concert, patrons can listen to a concert by duo flutists Chiara and Juliana Concini, as part of the ESO’s Musicians in the Making program; after the concert, “guests are invited to sit down, relax, and engage in a casual conversation with Lucas Waldin and pianist Daniel Fung in the main lobby.  Sunday Coffee Shop offers a uniquely interactive Q&A setting with our Resident Conductor and guest artists this season.”  edmontonsymphony.com
