GRIME artist Solo 45 has been found guilty of raping four women and imprisoning them.
The rapper, whose real name is Andy Anoyke, got a kick out of filming his victims suffer and would terrorise them.
He waterboarded one victim, beat her black and blue and held a gun to her heard.
The rapper, 33, was a violent and controlling narcissist and a bully, jurors heard.
In vile video clips played to the jury, Anoyke is seen interrogating the women about previous sexual partners, slapping them, insulting them and raping them.
Anokye, of Bristol, said he loved rough sex and all the women consented.
He was unanimously convicted of 30 charges, including 21 rapes, five counts of false imprisonment, two counts of assault by penetration and two of assault occasioning actual bodily harm.
Prosecutor Christopher Quinlan, QC, told Bristol crown court each victim suffered in similar ways at different times.
He said: "He imprisoned, assaulted, sexually violated and raped four women.
"Each suffered in similar ways at different times at the defendant's hands.
"He filmed, using his mobile phone, a great deal of what he did.
"He is a sadist who derives satisfaction and sexual pleasure from inflicting pain and suffering."
Anokye rose to fame in 2014 with the track Feed Em To The Lions.
He has performed with the likes of Stormzy, Skepta, Wiley and JME and he started out as part of the grime crew Boy Better Know in 2006.
Judge William Hart adjourned sentencing to a date to be fixed and ordered a psychiatric report to be carried out.
