[Machine Translation] The Boys Choir, Czech Boys Choir "Boni Pueri" commemorates their visit to Japan. The repertoire includes European love songs and classical pieces, which are their forte, as well as Czech works. The boys' voices are pure and clear, and the bass part of the young men's voices overlap, creating a thick harmony. In addition to a cappella, arranged versions with piano and organ accompaniment are all sung in the original language.
