The Russian invasion won't stop the music in Kyiv. Musicians gathered Wednesday to hold an outdoor concert outside the Kyiv-Classic Symphony Orchestra - performing the Ukrainian national anthem and other songs despite the advance of Russian troops. The musicians are part of the Ukrainian National Tchaikovsky Academy of Music, where about 50 students and staff are staying in the academy's dormitory rather than risk going home. One orchestra member said "We are showing our strength through music". What are some songs that inspire you in difficult times?
