One of the most difficult trophies in the game, as you are required to play on Expert difficulty and achieve an “Off The Chain” or 5-Mic Performance. It is possible to combine this with ‘All Eyez On Me’. My suggestion is to pick your very best song. Personally, I used Method Man & Mary J. Blige’s “You’re All I Need” since the singing parts are so easy it’s like free points.

Similar to "All Eyez On Me" achievement, except you do not have to turn the vocals off. So pop it on Expert difficulty, and choose "Yes" for vocals. This makes things much easier, as you still have the rapper singing to sing along to at least. The best recommendation I can make is to choose the song you know absolute best. Aside from that, practice and be sure to hit 5 mics. The achievement pops at the results screen.
NOTE: You can obtain both this achievement and "All Eyez On Me" in one attempt if you can manage to hit 5-mics on Expert with Vocals set to "No". Follow the guide for that achievement if you wish to attempt it that way.
