Question: What is the birthdate of this American musician, who sings with Alice in Chains on the album A Looking in View?
Context: "Heaven Beside You" is a song by American grunge band Alice in Chains, from their third album "Alice in Chains" (1995).  The song was included on the compilation albums "Music Bank" (1999), "Greatest Hits" (2001), and "The Essential Alice in Chains" (2006). "Over Now" is a song by the American rock band Alice in Chains, released on their album "Alice in Chains" (1995).  It was a single from the band's "MTV Unplugged" performance, and was used to close the televised broadcast.  The B-Side consists of the original studio version of the song.  This is the second longest song that Alice in Chains has released as a single, behind "A Looking in View". 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, and was the follow-up to the highly successful "Dirt".  As with their previous releases, the album's songs focus on heavy subject matter such as depression, isolation, drug use, 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 metal vibe. William Bradley DuVall (born September 6, 1967) is an American musician, best known as being the current co-vocalist and a rhythm guitarist for the alternative metal band Alice in Chains replacing original vocalist Layne Staley, who died in 2002.  DuVall joined Alice in Chains in 2006, and he appears on the 2009 album "Black Gives Way to Blue" as well as the 2013 follow-up "The Devil Put Dinosaurs Here".

Following a worldwide tour in support of its previous album, "Black Gives Way to Blue" (2009), Alice in Chains began work on a new album.

The band entered the studio in July 2011 to start work on their fifth album.  During the writing and recording sessions, guitarist Jerry Cantrell underwent shoulder surgery, which resulted in the delay of the album.  The recording sessions of "The Devil Put Dinosaurs Here" were completed in December 2012. "Grind" is a song by American rock band Alice in Chains and the lead single from their album "Alice in Chains" (1995).

The song was included on the compilation albums "" (1999), "Music Bank" (1999), "Greatest Hits" (2001), and "The Essential Alice in Chains" (2006).  Jerry Cantrell sings lead vocals on the song with Layne Staley harmonizing with him. James Bergstrom is an American musician best known as the drummer for the band Second Coming.
