Since the start in 2008 Jon Wesseltoft and Lasse Marhaug, aka Tongues Of Mount Meru, have released a set of intense and mind tripping longform pieces. Their music often almost seemingly static and gradually building it's intensity over long streches of time. This is music that demands concentration, and hypnotically drill into the awareness of the listener. At times abrasive and intense, but also beautiful and calmly introspective. In 2022 they released the culmination of older work with the monumental 4CD box 'Naga Mountain' (Holidays Records) consisting of material from 2008 to 2011. After a longer hiatus they started recording again in the spring and summer of 2021. First came the over 2 hour long 'Lalit (2:14 Version),' being based around the Indian raga 'Lalit,' on the Italian Superpang label. Now they return with the latest culmination from those sessions with the 100 minute piece 'Kalpa.' This being probably their most heavy and crude outing to date. With more focus on actively fusing larger sections of almost clustered sound together with tonal activity. This without loosing the consistency of the longer stretches of overarching microtonal interaction. At times sounding like a churning minimalist nightmare ritual, but on the other end, a beautiful but heavy duty trance inducing drupad veena performance on half speed.
