the song is off the "gang related" soundtrack and is called "free 'em all". it's actually the other way around than in that video. it's a j-flex song although realest has the first verse. and it features realest, but under his old alias, "tenkamenin".
i mean to think i've heard this beat on a pac remix from the mixemup days but i may be mistaken. that might possibly mean there's a 12" with the instrumental on it, or better yet, a cds/cdm.
