Pianobasso's low-key and stripped-down arrangements of classical pieces has brought them international success with many listeners all over the world. This time they have chosen to go a little outside their established concept and instead record Christmas music consisting of Christmas carols and art music with a Christmas theme. The album is called Tranquillo - Sacred Christmas and will be released on November 22. Pianobasso is a duo that consists of pianist and arranger Thomas Gustavsson and double bassist Andreas Gustafson. On their previous albums, they perform well-known classical choral and orchestral works with their own arrangements and a personal expression, which means that they do not always follow the usual norms for this genre.
