it's not only a style change, some artist i know from here just get so much worse over time it seems. it's like you can hear the drag/boredom/rut or something.
what i dont understand is, how can you make a really good baseline all the time that is really involved with your track, full of life and then years later make it so dull, boring, stale, distanciated. its so hard to think they dont have the capacity to hear that themselves. the only thing i can think of is just not caring, and THAT might be what stings/offends people.
