Dark Spring
Opera in 11 Scenes after Frank Wededekind's
Lyrics by Joshua Clover
Nationaltheater Mannheim 2020

“a finger on the pulse of modern issues”

“an aching, sometimes disturbing work”

Musical America

“From the downbeat the mastery of orchestration that Thomalla wields is evident. The composition, execution, and performance are unparalleled.”

Music City Review

"This avowed song-opera goes like a bolted arrow directly into the listener’s heart"

The Whole Note

“I want to go over the meadows in the twilight…” sings Wendla (Lavi) in another of those moments where Thomalla allows a voice to shine, and to a melodic line whose beauty goes on after the closing bars."
