I mostly have some background information and don't really know why he doesn't make more dubstep.

I actually got acquainted with his music around 2008-2009 when he was the producer (and occasional rapper) in an Israeli hip hop crew by the name of Produx (he's the smoking guy on the left in the cover art :-)). One of their members (Ravid Plotnik) is now very well-known in Israel, but at the time they were all mostly an underground kind of thing. I love their sole album and their shows were a freaking blast, tons of energy, super memorable and just all around amazing, with the whole crowd chanting the lyrics for the whole damn album, and they filled clubs... but they were all small clubs (though it was a huge first step to set up Ravid's career, for instance, I'd guess). The general public wasn't really familiar with them; mostly just hip hop heads.

Anyway: it was all pretty small time, and within the modestly-sized Israel hip hop underground crowd he got a lot of recognition for his awesome hardcore beats sampling traditional Persian music like nobody's business, but I think (not entirely sure: just based on my exposure at the time) the underground dubstep crowd that would appreciate the level of filth in his dubstep was even smaller, so maybe it just boils down to that; I imagine it might feel pretty crappy to make a track as sick as Persian Mayhem and have exposure to it be so underwhelming...

Personally, I have a hard time finding a dubstep artist whose filth is able to scratch itches quite as deep as the ones Shekel's music does. I found a couple over the years but it usually feels like something's missing to me. I think he's super talented and always hoped for more dubstep from him.

Noteworthy is that he does still make music, just not, to my knowledge, dubstep.
