I know that there are a lot of songwriters which doesn't spend too much time in the studio or their songs ended up scrapped most of the times... like Ammo. But what happen with these producers that are impossible to track in social media or in its wikipedia page (which I don't trust much either); there's two cases where I couldn't find any trace of new work of them:
GoonRock, do you remember this black guy which appeared (and even featured in the title) in the songs he produced? Both LMFAO's CDs and Fergie's single "A little party never killed nobody" and some Carly Rae Jepsen's songs, he has some sick beats but he hasn't done anything in the last 4 years according to wikipedia. I *think* he's now called Listenbee in social media, but his new sound it's something completely different from before and it's been inactive from like a year or so, I don't get the point on even starting a new twitter account with a different surname.
The other case is Sandy Vee: This french producer was found by David Guetta and produced a lot for his album One Love, then he did an amazing job on his own and with Stargate but he's nowhere to be found in the last 2 years, he used to be active in social media and produced a few songs every year, now it's like it's gone.
This may be pointless but I like finding music by producers, and when producers stop working I want to know why.
