I'm compelled to write this review in response not only to the damning review from C. Allen, but also to other people I know who say this album is difficult. This album from Flying Lotus does indeed traverse a wide variety of sounds and musical ideas and as such some may reasonably comprehend this as being 'messy'. He eschews standard song forms with refrains/repeats and instead tends towards a continuous evolution of diverse musical ideas. Los Angeles also had this sort of through-composed approach but what makes this album an altogether more challenging listening experience is primarily due to the broader palette of sounds in Cosmogramma. Examples are ping pong balls, scat singing, video game sounds, the harp, trademark Flying Lotus synth sounds and so on. My words can't really do it justice - listen to the first 30 seconds of the album ('Clock Catcher') and you''ll get the jist of what this album's about.
This album is a strong example of the new areas being chartered in music in the 21st century. You've got strongly varied, experimental drum beats and rhythmic sounds which could be compared with Aphex Twin, but strike me as more soulful/jazzy. But beyond that you have this sonic exploration which I strongly believe is one of the most exciting realms of musical innovation still open in music (classical, jazz, dance, all music). Flying Lotus is one of many documenting these explorations in his work, but what sets him apart is that he is wrapping it up within the dance/electronic music and jazz genres. There are many artists also working with sound and producing more experimental sounds but what Flying Lotus is doing in an album like this is cementing these experimentations into a more appetizing and exciting output.
To label it 'amateurish' demonstrates extreme musical naivety - I can only assume that this is the comment of a non-musician who therefore shouldn't be passing judgement on the artist's technique. This is an album that exemplifies exceptional composition skill. Let me give as an example his reuse of themes. To establish unity in the album as a whole, there is a focus on harp glissandi (e.g. linking a high and low note by running through all the notes in between) and the reincarnations of it within the electronic sound spectrum. Littered through the album you will hear these: the first three tracks have electronic glissandi, the harp features prominently in the middle tracks , in the background of 'Mmmhmm', and on 'Recoiled' too. It is one means of linking the disparate sounds in the album together. Another aspect of compositional skill I would point to is the broad ranges that are covered within the music, and the texturing of the different parts is generally very good. This is not the work of an amateur.
If you're [still] reading this review and don't own the album I would strongly recommend it. As other reviewers have pointed out, it may not be for everyone - we all have our different tastes in music. It can also be challenging to listen to, but that's a good quality in this instance. Listen to it again and again and learn something new about it every time. Beats listening to Britney. You can put this on in the background and go about your business without paying too much attention, or you can engage with the music and follow it's every progression. Either way, I think it's great. 5 stars!
