Agneta Nilsson is an interesting step in Heldon's development: it gives a twist to their classic sound, which was mainly built around Pinhas' Fripp-esque guitar work and ambiental synth experiments, to began explore a more rhythmic territory. Drums and bass take more presence here, offering a "rockier" feel, but somehow retaining the mysterious ambience of its predecessors, while adding an extra touch of sinister aggressivity. Featuring among others Magma's keyboardist Patrick Gauthier, it starts pretty much in the same ambiental, spacey, minimalist electronic mood of the previous Heldon releases, but as the development of the main title "Perspective" goes ahead the move towards the more guitar + drums sounds of the next to come Heldon sound is evident.
