The project Largo is made up of a perfect and coherent fusion of different worlds; every one of the various musical fields supports, and revives the other. Sensual and innovating but nor cold or calculator, this music is creative and dynamic.

What makes the music of Largo so distinctive is Gast Waltzing's personal vision as well as his very unique way of scrutinizing jazz music. He states: I'm always a musician. It's not like I wake up and decide where to schedule music in. It is always present.

The band has performed at many prestigious Festivals and venues such as the Clearwater Jazzfestival, Hildener Jazz-Tage, Sibiu Jazzfestival, Blues & Jazz Rallye, European Jazzfestival in Athens, EU Music Festival in Hanoi etc.
