Final answer:
While the band Beethoven's Nightmare was not discussed, the provided information describes the Odessa Philharmonic Orchestra and Opera Chorus's unique performance of Beethoven's "Ode to Joy" in a fish market during a time of political tension.
Step-by-step explanation:
The band Beethoven's Nightmare is not specifically mentioned in the provided information, which instead describes a noteworthy event in March 2014: a spontaneous performance by the Odessa Philharmonic Orchestra and Opera Chorus. This event is notable due to the unique choice of location, a fish market in Odessa, and the timing, as it occurred during a period of political tension in Ukrainian and Russian relations over Ukraine's efforts to align with the European Union. The musicians' rendition of Beethoven's "Ode to Joy" from the Ninth Symphony served as a symbol of hope and unity amidst the unfolding crisis, as Russian troops took control of a Ukrainian airbase in Belbek. While not directly related to Beethoven's Nightmare, the spirit of using Beethoven's music for inspiration during challenging times is in itself a unique and powerful gesture.
