Up until 2010 Zatox was one of my favorites. He had great melodies and atmospheres, nice vocal parts to sing along (or shout things like I HATE YOU SO MUCH RIGHT NOW, AAAAAAH, always loved that shit), combined with pretty powerful kicks that completely suited his tracks. They were the complete hardstyle package. Musicality, inspiration, feelings, energy, great reverse basses with their drive... Man he was good.
After that, couple of exceptions in 2011 tho, it looks like he's just playing around a bit with his computer and doesn't put any feeling or music into any of his tracks. It's just cheap vocals, either weak or extremely overdriven/overly present kicks and very simple or even absent melodies. Sometimes there's a weak attempt at mimicking a style another producer used in a new track that people liked.
It just looks like a complete lack of inspiration. It's like he had a personal muse back in the days, which decided to abandon him around 2011, never to return. He had a few great tracks in 2011 and 12, in which he reaaaally messed up the kicks by pitching them way to high.
I still miss the old Zatox. But we pretty much buried him in 2012.
