Not one to leave its old music alone, Chicago heavy metal band Disturbed just released “The Lost Children” while on hiatus. The album, featuring B-sides and covers, fits into Disturbed’s recognizable style: riffs are aggressive and groovy, and the vocalist employs a percussive singing style that goes along with the beat.

“Black Ice,” AC/DC’s 16th studio album, is both a triumphant return to form and more proof that AC/DC is the most consistent band in history. They have been touted as fathers of heavy metal, punk rock, blues and straight up rock and roll and have managed to handle all of these labels with a suitable amount of swagger.
