I like all the tracks. Just not together,
The EP part sounds nice in spite of not fully jiving with the base, tone-wise.
That clav track, Though.
It doesn't blend because it's not playing the same progression.
I get that it's about the rhythm, but the keys must match (or be complementary).
If you listen with all the drums muted, you'll have a much easier time telling if your tracks are working. Most of the time, if any two layers of sound are clashing, it will effect the whole track. Better to cut too much than too little.
Hope that helps.
thanx for the feedback!
