Alice in Chains (occasionally informally referred to as The Dog Album,The Dog Record, and Tripod)is the self-titled third studio album by the American rock band Alice in Chains. It was released on November 7, 1995 through Columbia Records, and was the follow-up to the highly successful Dirt (1992). This is the band's first full-length studio album to feature bassist Mike Inez; their last album to feature original lead vocalist Layne Staley, who died in 2002; and their last album to be released on Columbia Records. The album debuted at No. 1 on the Billboard 200 and stayed on the chart for 46 weeks. The tracks "Grind", "Heaven Beside You" and "Again" were released as singles. "Grind" and "Again" were nominated for the Grammy Award for Best Hard Rock Performance. The album received double platinum certification from the RIAA and has sold over three million copies worldwide. The mockumentary The Nona Tapes was released to promote the album and became a cult hit. 　　As with their previous releases, the album's songs focus on heavy subject matter such as depression, isolation, drug use, relationships, anger and death. The band relies less on metallic riffs and more on melody and texturally varied arrangements, integrating some of the more delicate acoustic moods of their EPs.However, the riffs are mostly down-tuned and atonal, employing a strong doom and sludge metal vibe.
