SLIPKNOT's first full-length concert album, "9.0 Live", has been certified gold by the RIAA (Recording Industry Association of America) for shipments in excess of 500,000 copies. The CD, which was recorded at shows in Singapore, Japan, and Las Vegas, has sold 163,000 copies in the United States, according to Nielsen SoundScan.As previously reported, SLIPKNOT have been nominated for a Grammy for the sixth consecutive year. The single "Before I Forget" from the band's third album, "Vol. 3: (The Subliminal Verses)", was nominated for Best Metal Performance alongside songs by MINISTRY, MUDVAYNE, RAMMSTEIN and SHADOWS FALL — all bands that SLIPKNOT have toured with. SLIPKNOT have yet to take home a Grammy trophy, having competed in previous years with such heavy-hitters as METALLICA. The 48th Grammys will be awarded in a telecast Feb. 8 on CBS from the Staples Center in Los Angeles.
