Is grunge back, or did it ever leave? South African band Seether closely follows other post-Nirvana sad-sack outfits like Staind, trading off minor-key rockers with minor-key power-ballads on its 2002 debut album, Disclaimer. This exact formula has repeatedly served to spring the band straight onto the Billboard charts, where it had a big hit with “Fake It” from 2007’s Finding Beauty In Negative Spaces. The group travelled to Nashville and tapped producer Brendan O’Brien for its just-released follow-up, Holding Onto Strings Better Left To Fray. The disc’s first single, “Country Song,” is another slice of gussied-up grunge, albeit with a twangy, southern-fried guitar riff.
