Jääportit is Tuomas M. Mäkelä (keyboards, music and sound) and Mindy M. Heinonen (violin, voice and visual art) from Tampere, Finland. Originally formed in 1997 as Tuomas' solo project, the now-duo creates mostly instrumental music that combines styles from cold atmospheric ambient electronica to frostbitten post-rock.

Band uses both synthetic and natural sounds to create frosty, fragile, bewitching, polarizing, deep, atmospheric, transcendental, moving, serene, layered, esoteric, powerful but soothing music to keep you afloat in the astral stream.
