The starting point for the project was Oskar experimenting with sinus tones and binaural beats. Most of the song titles are derived from different beat frequencies which correspond to the frequencies of brain wave activity in different stages of wakefulness. The original plan was to start at high frequency and decrease the intensity with every song. To make the album more balanced this idea was rejected, but the sinus tones and frequencies are still the fundamental base of the songs.
The second part of making the record consisted of implementing more vivid elements in the form of field recordings, analog synthesizers and processing with tape echoes and pitching with a cassette deck. A rather significant aspect of the composition is that the played instruments (e.g. synths, guitars, saxophone etc) are not bound to a key or fixed tempo but adapted to the field recordings and sinus tones, both in harmony and tempo, which gives the songs a free and natural flow.
’Astral Planes’ is Oskar Karlström’s debut as a solo artist. However, he is a member of Swedish shoegaze duo Bolywool, the trio Sonores and ambient dream pop duo Droyma.
