Proper Dos is a Mexican-American hip hop group composed of Frank Villareal (rapper), Ernie Gonzalez (producer), "Big Bass" Brian (mastering), and Stuart Wylen (bass guitar, keyboards, congas). The group released an album, Mexican Power, in 1992 on Rhino Records. After this came We're at It Again in 1995, Heat in 1998, and Overdose in 1999.
A street-style group; Proper Dos' main lyricist is Frank Villareal. However, Proper Dos has also had help on some recordings by special guests including Big Shady, Lil Rob, Point Blank, Royal T, Knightowl, and others.
In 1992, the group finished their potent debut album, Mexican Power, under the Rhino Records label. "One Summer Night," "Life of a Gangster," "No Turning Back," and "Hard Time" are a few of the hip-hop/chicano rap mixed numbers on the debut.
Proper Dos recorded a number of singles, and then finally, three years later, came a second album, rightly named We're at It Again, released by Skanless Records. Another three years went by before the album Heat hit the store shelves, followed a year later by Overdose. The album Overdose carries numbers like "Shake the Ground," "We Run This Mutha," and "Can You Rock Like This." Many of the tunes have explicit lyrics.
