Sweetnighter is the third studio album by American jazz fusion band Weather Report, released by Columbia Records in 1973.

Zawinul began to assert greater control of the band, steering it away from the collective improvisation that marked its live performances toward more structured compositions emphasizing funk and groove.

Sweetnighter is considered to be the most stylistically transitional release by the band as it bridged the gap between the more open, improvisational earlier style to a more compositionally structured format.

Zawinul had taken the decision to add some funky beats in the band's sounds, so he recruited drummer Herschel Dwellingham and percussionist Muruga Booker to play on the album.

So while I'm pleased that they're going for a drum groove a little solider than anything Dom Um Romao can move and shake, I'm not surprised that they get it only—just barely, in fact—on '125th Street congress.'
