2. The two you mentiond plus

Asia

that first album was fantastic. The next one OK and the rest, well, good thing they had that first album.

But I saw them at a Hard Rock Live a few years ago and they put on a great show.

Also, Brujeria:

Brujeria is an extreme metal band formed in Tijuana, Mexico in 1989. Their name comes from the Spanish word for "witchcraft". Their songs, which are sung in Spanish, are focused on Satanism, anti-Christianity, sex, immigration, narcotics smuggling, politics.
Brujeria is a side-project of guitarist Dino Cazares (founding member of Fear Factory), and has featured artists such as Billy Gould, Nicholas Barker, Raymond Herrera, Jeff Walker and Shane Embury. They perform under pseudonyms and portray themselves as a Latino band consisting of drug lords, concealing their identities due to being wanted by the FBI. Their lineup has changed over time and could be different at any point in time.
