California-based hardcore group the Bronx have created a truly awesome album with their fourth full-length record. After creating two punk-meets-mariachi albums in 2009 and 2011, respectively, the Bronx have returned to the grit with 'The Bronx (IV),' and it's being streamed in full online.

The Bronx attacked the underground punk and hardcore scene with their first full-length in 2003, boasting powerful modern classics such as 'False Alarm,' 'Heart Attack American' and 'They Will Kill Us All (Without Mercy).' The band released two more albums before venturing into mariachi territory, but now the Bronx are back to hard-hitting and catchy hard rock tracks with their 2013 album.

'The Bronx (IV)' showcases a more melodic style than their grittier-than-dirt sound 10 years ago. Drummer Jorma Vik explains this change, along with how it's affected the performance of vocalist Matt Caughthran. "Matt doesn't scream as much, but he's got that thing in his voice where he can scream in pitch," Vik describes to NME. "Mariachi has helped his confidence as a singer and ours as songwriters."

This album is definitely a must-hear recording, and may even become one of the defining underground rock albums of 2013. We certainly love it, so we give 'The Bronx (IV)' our seal of approval and highly recommend you give standout tracks such as 'Along for the Ride,' 'Too Many Devils' and 'Torches' a good listen courtesy of Rolling Stone.
