Here are this week's notable new releases.

Courtesy Nacional RecordsTodos Tus Muertos is an iconic Argentine rasta-punk band. They've been around since 1985, so there's plenty of good material to pick from in this collection of their greatest hits.
Duranguense's K-Paz de la Sierra has been through a lot lately. In May the band divided up due to disagreements then, in December, 2007, lead singer Sergio Gomez was killed. Between all their troubles, a new studio album would be too much to ask for. Here's a live album that was filmed last year for K-Paz fans.
Latin music - especially Brazilian - plays a big part in the lounge music scene. If you like this type of music, this looks like a good album with lots of tracks by Panaphonic, Safari Ways, Pauline London and more.
Una Calle Nos Separa is the debut album by a new group from Chihuahua, Mexico that's just signed with Univision's Disa Reccord label. From what I heard on their 'myspace' page, this is pleasant pop-style cumbia. Listen to the group and judge for youself.
Listen to Cumbia Che
Los Rieleros del Norte (Raiders of the North) is a pioneer norteno band, founded in Pecos, Texas, although the band members are originally from Chihuahua. They've had many hits over the years and it's a good bet that this album will be another.
A popular rock band from Spain, M-Clan, is back with their first studio album since 2004.
