Refreshing
I like how this song isnt following current trance/techno trends by using uncommon instrumentals.. I guess thats the beauty of underground shitt tho. I think the song does get too repetitive though.. I think if u could make another song like this, but only use that tune that plays throughout this whole song for a while at the beginning and make it fade into some next techno that keeps getting crazier and crazier until the beat gets u into a good trance then either slow or stop the music at the end and play that tune again to finish the song with a potentially amazing effect...
oh yea i would suggest using these instruments again and if u can make it sound good maybe even toss in a few more sounds if possible to add some more variety.. orr if ur feeling especially talented u could even try throwing in new sounds as the song progresses
sorry maybe im suggesting too much but theyre just to give u sum ideas if u perhaps need them cuz i really do see a lot of further potential in these songs.
