Heavy Weather is the eighth album by Weather Report, released in 1977 through Columbia Records. The release originally sold about 500,000 copies; it would prove to be the band's most commercially successful album. Heavy Weather received a 5-star review from Down Beat magazine and went on to be voted jazz album of the year by the readers of that publication. Featuring the jazz standard "Birdland", the album is one of the best-sellers in the Columbia jazz catalog. This opening track was a significant commercial success, something not typical of instrumental music. The melody had been performed live by the band as part of "Dr Honoris Causa", which was from Joe Zawinul's eponymous solo album. Although not mentioned as a live recording in the liner notes, "Rumba Mamá" (a percussion and vocals feature for Manolo Badrena and Alex Acuña) was recorded at the band's concert in Montreux in summer 1976, of which a film would be released on DVD in 2007.
