Hey I'm listening to Liquid Journeys right now, before I clicked this thread - cool coincidence! It's the first time I've heard it and I'm liking it - much more so than Shpongle which is barely musical (imo! Don't flame pls! :D). But really, it's just noise
You guys might already have heard my recommendations but I'm putting them out there for the off chance that you haven't. They're not exactly comparable to Shpongle but may suit your tastes.
Carbon Based Lifeforms
Simply sublime, they have a great discography accessible on YouTube. I recommend them highly!
Carbon Based Lifeforms Interloper [Full Album] - acid/downtempo/ambient
Carbon Based Lifeforms Hydroponic Garden [Full Album] -downtempo/ambient/psychedelic
And other albums to be found you know where.
Bluetech
Another artist worth a listen is Bluetech; their music is psychedelic/ambient, complex and subtle, the kind that grows on you the more you listen. If you give them a try, you've got to have patience really, it's not that kind of mainstream instant-gratification music, but there is much underlying beauty to be enjoyed.
Bluetech Basement Dubs [Full EP]
Bluetech Cosmic Dubs [Full Album]
Lots more albums on Youtube.
Ott
You might like this, it's a bit crazy, certainly more Spongle than my other recommendations.
