If you had to introduce someone to Houston hip hop, what artist & song would you throw their way?1

I recently moved out of H town for work. The new boss lady said she's really into hip hop and gangster rap, but has never heard of DJ Screw or any Houston rappers other than Travis Scott. There's too many good artists and songs out there, so for that I ask…

If you gad to introduce someone to Houston hip hop with only a few songs, what jams are at the top of your list?
