Long Tall Weekend is the seventh studio album by American alternative rock duo They Might Be Giants, released in 1999. It was released exclusively online through the digital music service eMusic. The album was the band's first since their departure from the major label Elektra.Long Tall Weekend was also the first full-length album released exclusively on the Internet by an established major label band. Although the album's primary release was digital, CDs of the album were issued promotionally. Following the success of the album's release through eMusic, TMBG went on to issue a digital series of rarities collections — TMBG Unlimited — through their website.
Many of the songs that appear on Long Tall Weekend existed as demos and selections from the band's Dial-A-Song service. "Drinkin'" was originally written six years prior to the release of the album. "Maybe I Know" had been in TMBG setlists since the 1980s. Many songs were intended for release in different forms on later albums. "She Thinks She's Edith Head" and "Older" resurfaced on Mink Car in 2001. The next year, "Rat Patrol," "Token Back to Brooklyn," "Reprehensible," "Certain People I Could Name" and "They Got Lost" appeared on the rarities compilation album They Got Lost, and "The Edison Museum" appeared on No!. "The Edison Museum" was originally written and recorded in 1991 and featured on the Edisongs compilation that year. The recorded version appearing on Long Tall Weekend is largely the same as the Edisongs version, though the mixing varies.
Some songs, such as "They Got Lost" and "Lullaby To Nightmares" had also existed in different forms prior to the release of Long Tall Weekend. The former was a live track with a much faster tempo from the band's live compilation Severe Tire Damage.
"They Got Lost" and "Certain People I Could Name" were both originally slated for inclusion on Factory Showroom.
Following the digital release of Long Tall Weekend, They Might Be Giants became the most downloaded band of 1999. John Flansburgh speculates that the feat was based not only on the content of the album, but also on the band's early willingness to embrace digital formats, having been urged to do so by the Restless Records label.
The album received generally favorable reviews from critics.
