"Mama" was the first single from Genesis' 1983 self-titled album (often referred to as the "shapes album" or simply "Mama", after the first track). Instantly recognizable from its harsh drum machine introduction, which leads into minimalist synthesizer lines in minor keys and finally Phil Collins' reverb-laden
voice, "Mama" serves notice that the album which follows will be
considerably darker than previous efforts. It remains the band's
biggest commercial success in the UK, peaking at #4 on the UK Singles Chart, but was less popular in the US, only reaching #73 on the Billboard Hot 100.

The track also has a powerful final verse punctuated with a live
drum kit (modified by effects), comparable to Collins' earlier solo
recording "In the Air Tonight".

The song has resurfaced in 2007 as part of the Turn It On Again tour, albeit transposed down a key to account for the deepening of Phil Collins's voice over the years.
