Looking for songs that sound similar to these: SBB - Nowy horyzont (1975) - 08 - Dyskoteka (bonus) - YouTube Kraftwerk - K1 - YouTube to be more specific, songs that are instrumental, progressive/fusion and have a serious/hardcore feeling to them. preferably from 60s/70s. like serious fusion type stuff similar to the birds of fire album too by Mahavishnu Orchestra. If anyone understands what i mean pls post, thx! and if you haven't heard those two awesome songs yw!
