She's definitely more known than Stush, and was better known than Lady Sov first! She was one of the first grime MCs to get a major label deal and an album out, was cast as the "female Dizzee" when grime was still really young (ie, I was still in Cardiff - Sov on the other hand didn't come close to blowing up until way after I'd moved to London) and even scored a top 40 hit off it. Her profile declined after that cuz no one, either in the scene or the mainstream, thought the album was any good at all. (I think it's OK, suffered from the standard set by Boy In Da Corner but no worse than most other inconsistent 'urban' albums and loads better than the crossover shite people are coming with now.)

I also did a potted history of Shystie here already with youtube links &c, ahem ahem.

As for DJ Assault, I should know much more about him...I've seen him live though, it was BANGING. One of my DJ friends absolutely idolises him.
