Kristoffer Lo (born 19 February 1985 in Moss, Norway) is a Norwegian jazz musician (tuba, flugabone, guitar, keyboards) and composer.

From its traditional role as the low-end in symphony orchestras and Dixieland bands, he has taken the instrument to a new direction, filling the position as the ultra low end in metal- and noise bands.

With a bunch of electronics and huge amps, Kristoffer’s tuba sounds like a low-end monster and a high pitched squeal at the same time.

He is a part of bands like Pelbo, Trondheim Jazz Orchestra, Microtub, Sunswitch and Highasakite.

[2][3] With music studies from the jazz program at the Musikkonservatoriet i Trondheim, he has slowly built up a solid reputation both in Norway and elsewhere.
