Premise: Flyin' the Flannel is the fourth album by the American alternative rock band Firehose, released in 1991, and the band's first album after signing with the major label Columbia Records. It is considerably different in sound from its predecessor, "Fromohio". In 2014, the album placed fifth on the Alternative Nation site's "Top 10 Underrated 90’s Alternative Rock Albums" list.
Hypothesis: Flyin' the Flannel outsold all other albums in 1991.
