Well made. Sense of speed. But dodgy loop.
Unlike 'Dark Sub Woofer', which I'd rate 9 or 10 in terms of looping, I'd give this an 8 at most - there's a bit of a gap. Not so much that it's unusable, but definitely enough to make it a bit of a distraction. Also, the way it's slow for a few bars before speeding up doesn't help its cause at all.
I do like the lead melody - enough variation to keep it interesting, whilst enough repetition to keep it in the bg.
When the faster beats come in around 0:28, that's cool. I also like your 'whooooooooooo' around 0:40.
Definitely a melody-led 'loop', this has a good sense of speed. It reminds me of flying over a desert, or maybe high above some forest.
Apart from the slightly annoying loop, it's really tightly produced. Fun to listen to.
Please contact me if you would like to use this in a project. We can discuss the details.
