The "RELAX WITH INSTRUMENTAL HITS" edition continues with a brand new title, this time accompanied by a trombone. The sound of this instrument is very similar to the sound of a male choir, so it is not surprising that it also replaces vocals on this CD, especially in well-known musical melodies. Václav Šalbaba, a long-time member of the Classic Jazz Collegia and Milan Svoboda's Prague Big Band, will perform on the trombone.
