Madness - Coachella 2012

Madness is a seven piece ska/brit pop band that formed as The North London Invaders in 1976, and then changed names to Morris and the Minors, and then Madness, in homage to ska/reggae artist Prince Buster. The band is notable for being one of the most prominent bands of the 2-Tone ska revival(the second wave of ska, fusing elements of ska, punk rock, rocksteady and reggae) in the late 70's in the UK and for being on the UK singles chart for 214 weeks over the course of the 1980s decade.

Madness sings about some very strange subjects, but also some activist stuff. They sing about everything from childhood to politics to weird fetishes and abnormal families and other touche subjects.
Also one of the most interesting things about this band, is that 75,000 fans at their reunion concert in Finsbury Park, London on August 8, 1992, caused nearby apartment towers to shake and feel like an earthquake, read about it in an interview with the lead vocalist Suggs here: http://www.virtualfestivals.com/latest/interviews/3325

Just like any other band founded in the 1970s and active on and off since then, Madness has a large and dedicated fan base and too many albums and EPs to list in a short segment, and since they are also a seven piece band with members popping in and out of the line up over the years, too much drama to go into a storied history. Instead I will do something a little different and just give you a list of probable songs they will play live and a copy from Wikipedia of current members and their active times in the band:
Graham McPherson – Lead vocals (1977, 1978–1988, 1992 on)
Lee Thompson – Saxophone, percussion, and backing vocals (1976–1977, 1978–1988, 1992 on)
Mike Barson – Keyboards, pianos, vibraphone, and backing vocals (1976–1984, 1992 on)
Chris Foreman – Guitar (1976–1988, 1992–2005, 2006 on)
Cathal Smyth – Trumpet, backing vocals, dancing, and occasional acoustic guitar (1979–1988, 1992 on); bass guitar (1976–1977)
Daniel Woodgate – Drums, and percussion (1978–1986, 1992 on)
Graham Bush – Bass guitar (2009 on)
