Weezer (2008 album): Weezer, also known as the Red Album, is the eponymous sixth studio album by American rock band Weezer, released on June 3, 2008.  Rick Rubin and Jacknife Lee both produced parts of the album, with the band producing a handful of tracks themselves.  Like the group's 1994 debut album, the Blue Album, other band members contributed to songwriting.  This is the first and, so far, the only Weezer album to feature lead vocals from all four band members.  The album also features more musical experimentation in comparison to their previous efforts, especially shown in such songs as "Dreamin'", "The Angel and The One" and "The Greatest Man That Ever Lived".

Feels Like Summer: "Feels Like Summer" is a song by the American rock band Weezer.  It was released on March 16, 2017 as the lead single for their 2017 album "Pacific Daydream".  The song was performed for the first time at the SXSW on March 17, 2017.

Weezer (2001 album): Weezer, also known as the Green Album, is the third studio album by American rock band Weezer, released on May 15, 2001, through Geffen Records.

Maladroit: Maladroit is the fourth studio album by American rock band Weezer, released on May 14, 2002, through Geffen Records.

The album features heavy metal riffs, uncommon to Weezer's previous releases.

Island in the Sun (Weezer song): "Island in the Sun" is a song by the American rock band Weezer.  It is the second single from the band's 2001 self-titled album "Weezer".  "Island in the Sun" was not originally planned to be on the album, but producer Ric Ocasek fought for its inclusion.  It was a successful radio single and perhaps the band's biggest hit ever outside of the United States, reaching No. 31 in the UK and No. 17 in France.  In January 2002, the Australian Triple J Hottest 100 ranked the song 7 in its 2001 countdown.  "Island in the Sun" is also the most-licensed track in the Weezer catalog.  In 2009, "Pitchfork" named it the 495th greatest song of the 2000s.

Weezer (1994 album): Weezer, also known as the Blue Album, is the eponymous debut studio album by American rock band Weezer, released on May 10, 1994 through DGC Records.  The album was produced by The Cars frontman Ric Ocasek and recorded in Electric Lady Studios in New York City.  The Blue Album was supported by three singles: "Undone – The Sweater Song", "Buddy Holly" and "Say It Ain't So", which brought Weezer mainstream success, helped by music videos directed by Spike Jonze.

Pacific Daydream: Pacific Daydream is the upcoming eleventh studio album by American rock band Weezer.  The album is set to be released on October 27, 2017 by Atlantic Records and Crush Management.  The lead single, "Feels Like Summer", was released on March 16, 2017.  On August 17, the promotional single "Mexican Fender" was released.

Make Believe (Weezer album): Make Believe is the fifth studio album by American rock band Weezer, released on May 10, 2005 by Geffen Records.  The album was considered to be a return to some of the emotionally vulnerable lyrics of Weezer's previous releases, and due to the strength of the hit single "Beverly Hills", the album was a commercial success.  In addition, "Beverly Hills" also gained Weezer's first Grammy nomination for Best Rock Song.  Despite this, "Make Believe" received mixed reviews from critics and fans, although it has remained a consistent seller.  The recording process of "Make Believe" began prior to the release of their previous album, "Maladroit"; however, it was prolonged compared to the recording of most of Weezer's previous albums, and lasted for almost three years.  Rivers Cuomo's songwriting on "Make Believe" was described as "[a] return to musical, emotional bloodletting", although the lyrics were noticeably more simplified than before.

Weezer discography: The discography of Weezer, an American rock band, consists of 10 studio albums, two compilation albums, one video album, six extended plays, twenty-eight singles and twenty-four music videos. Weezer's self-titled debut studio album, often referred to as "The Blue Album", was released in May 1994 through DGC Records.  The album was a huge commercial success, peaking at number 16 on the US "Billboard" 200 and spawning the singles "Undone – The Sweater Song" and "Buddy Holly", both of which were responsible for launching Weezer into mainstream success with the aid of music videos directed by Spike Jonze.  It has sold 3.3 million copies in the United States and has been certified triple platinum by the Recording Industry Association of America (RIAA), becoming the band's best selling album to date.  Following the success of their debut album, Weezer took a break from touring for the Christmas holidays.  Lead singer Rivers Cuomo began piecing together demo material for Weezer's second studio album.  Cuomo's original concept for the album was a space-themed rock opera, "Songs from the Black Hole".  Ultimately, the "Songs from the Black Hole" album concept was dropped; the band, however, continued to utilize songs from these sessions into work for their second studio album. " Pinkerton" was released as the band's second studio album in September 1996.  Peaking at number 19 on the "Billboard" 200, it was considered a critical and commercial failure at the time of its release, selling far less than its triple platinum predecessor.  However, in the years following its release, it has seen much critical and commercial championing.
