Kuoleman Galleria

Finnish Thrash Metal Patrol

RUINSIDE was formed in Tampere, Finland in the fall of 2005. After years of struggling with the line-up changes, the band finally found a solid basis for working professionally in 2010. The basic idea of RUINSIDE’s music style was formed and the band released their debut album ‘The Hunt’ in 2012 through Mighty Music, after releasing two demos and two EPs on their own.

Black ‘N’ Roll / Dark Metal act

In the world of KUOLEMAN GALLERIA there is no place for faith and hope arises briefly when you are scratching the last wet match desperately with your numb hands on a matchbox cover only to feel warm for a second. KUOLEMAN GALLERIA creates their music unconditionally and do not bow to any direction.

Acoustic cover band

AKUSTINEN OLOTILA is an acoustic rock cover trio. The band plays Finnish rock covers from different decades. Set list consists of Juice Leskinen, Hector, Leevi And The Leavings, Irwin Goodman, Eppu Normaali, Tehosekoitin etc.

Athmospheric Progressive Metal

Sargassus was established in 2012 by guitarist Teemu Leskinen and drummer Matias Rokio. Years of playing and practising together laid the ground for what Sargassus is today. The debut EP The Giant was composed over a period of 2 years and finalized when Matias Stenman joined the band on vocals in 2020. The new single Tiamat and the following EP The Albatross introduced improved production quality coupled with all the more progressive touch.

The band’s music combines progressive and heavy riffs with dynamic drumming and atmospheric interludes. Interestingly, most songs are composed intuitively in live jamming sessions by Rokio and Leskinen. Stenman is the crazy mastermind responsible for the poetic aspect of the songs and Jukka Teppola wakes up the lower (fretless) frequencies with his own elegant style. Thematically the band draws its inspiration from mythology and literature.


Raging Cannon also offers studio services. If you want to record drums or guitars for example to your demo with a budget price just send us e-mail or a private message through Facebook.
