“B+B Project” is a Ukrainian ensemble named for its instrumentation (button accordion and bandura, an instrument which combines qualities of the zither and the lute). “The bandura is a traditional Ukrainian instrument … the B+B Project is bringing back the popularity of this fine instrument!” (EthnoCloud). “The group was created (in) 2015. They play a diverse repertoire: original songs, cover versions, rock, classical music, dubstep, Ukrainian music, and many others … The collective has toured extensively in Ukraine and around the world.” The B&B Project is now one of the most famous instrumental groups in Ukraine.
The group released “Cheremshyna” in 2022. After beginning in A minor, there’s a shift up a full step to B minor at 1:53. At 2:27, the tune returns to the original key.
