In my opinion I don't think that Bone need DJ U-NEEK because in so many ways he seems like a shady character and he steals the credit from other producers.
Let's go through the years - Crossroads (U-neek remix) From a interview i heard from Dre Ghost on youtube he said that he came up with the concept for that and had everything done and gave it to U-neek to check out) and to be honest I believe it was Tony-C behind most of Eternal and Art of war but u-neek stole all of the credit for that. Another factor in this is you can tell who's style Bone is more adapted to by listening to the solo works that U-neek has produced example Krayzie Bone's Where my thugs at lets be honest the beat isn't great at all and then you hear Tony C's production on Krayzie's song Drama which the beat and lyrics are both great it's a winning combination.
U-neek also uses the same style over and over again listen to the piano riffs on murder one and then listen to the piano riffs on shotz to the double glock same thing with whom die they lie and east 1999 same guitar riffs.He does the same thing also with the remix of change the world and not my babby just in a different way maybe that's just the vibe he was in at the time.
Another point is on the Look into my eyes atlantis remix and if i fall if you look at the production notes of those songs it say produced by u-neek but it also says live instruments played by virgil i forgot his last name but i honestly do not think that u-neek has the musical talent to compose music like that and that he was just stealing the credit once again .
Even if he actually did do some of their production by himself it has suffered in the last few years pay what you owe is a great beat but the entire beat is sampled by the lakeside song i can't remember the name of at this time so really dj-u-neek just basically took a instrumental and looped it anyone can do that.
So in my opinion Bone made a bad decision by leaving Tony-C in the cold and going with U-neek he has even screwed them out of money by selling lame ass albums with the exception of the leathaface album but just making a profit for himself and i don't think he gives a damn about the group and that he just wants to leech off of their success.
