Konstantin Reinfeld and Benyamin Nuss are releasing "Merry Harmonica", a Christmas album that presents well-known Christmas carols in new, surprising arrangements. The idea arose spontaneously during a performance in Dubai at EXPO 2021. Reinfeld, who has been fascinated by the harmonica since his youth, brings the instrument to the album with emotional depth. The repertoire includes classic Christmas songs and international hits, reinterpreted in different styles such as jazz, blues and Latin. Prominent guest musicians such as Alma Naidu and Marc Marshall further enrich the album.
