I think your right in away and maybe not in others.
Besides Bam Bam neither of them to my knowledge have had a nice flow of records out in years. Bam Bam has made some good stuff but I think he's made crap as well. His stuff wit alex peace's vocals is awfull IMO. Dj Urban has'nt had a new record out in a while (you cant count the new remix ep on flux). His last one on subsounds was poor IMO.
Im very undecided about Lester Fitzpatrick, His best stuff is his Dj skitzo stuff I'd say but its pretty much impossible to come by. His record on Terry Mitchel's system label had two lethal tunes on it and I saw that he has a new one out soon to, which will be interesting.
As for Robert Armani i think the lad has made some of the best techno ever made. His big kicks and patterns are ****in deadly but where has he gone to?
Im a huge fan of Dj Urban's and Robert Armani's music but I'd really like to hear some new stuff from them because they make some brilliant stuff. I think these and some of the other Chi-Tech guys definitely deserve alot of credit for their contribution but I'd really like it to keep coming.
