Symphonie Fantastique is a work of opulent orchestral colors and effects that tells a “fantastic” story, starring Hector Berlioz himself, besotted with a Shakespearian actress. The passion-propelled story follows the love-sick hero’s drug-induced visions to a glittering ball, the march to the scaffold and a demonic Witches’ Sabbath with the Dies irae pounding out a hair-raising theme amid tumult. Conductor Giedrė Šlekytė makes her Dallas Symphony Orchestra premiere leading Strauss’ "Oboe Concerto," with Principal Oboe Erin Hannigan in the spotlight.
