Rap group from Pomona, California, USA.
Signed to Eazy-E's Ruthless Records in 1989 through the help of Lay Law. Their first Album was selected as one of The Source's 100 Best Rap Albums. With the single "Murder Rap" they made their breakthrough.
For the Tracks "4 The Funk Of It" and "Call It What U Want", the group can be considered as the "true founders" of G-Funk. After the 2nd album Go Mack left the group.
Their third and last album on Ruthless Records is regarded to be one of the best G-Funk albums ever released.
After Eazy-E's death the group switched to Tommy Boy Music and released two albums in 1996 and in 1998 on the label.
In 1999 they left Tommy Boy and went independent on their own record label West World Records and released one group album on this way. At the same time they made another short-lived record deal on Suge Knight's Tha Row Records (formerly known as Death Row Records (2)).
In 2004 Cold 187um also known as Big Hutch was indicted for conspiracy to traffic one thousand pounds of marijuana and put the group in complete silence. After Cold 187um's drop out in 2008 he released his 3rd solo album , presented by Above The Law. The long awaited 7th group album "Sex, Money And Music" was released in 2009, although the singles were released years before.

Currently they're working on their 8th group album called "Reloaded", containing production by Cold 187um, Tha Chill, Sandman and DJ Battlecat.
