One of the premier merengue acts of the 1990s, Grupo Manía rode the top of the charts during the style's mid-'90s heyday, and even though their star power dimmed steadily over the years, they continued recording albums for their core fan base and were regularly nominated for Latin Grammys. Formed in 1993 in Puerto Rico, Grupo Manía (aka GrupoManía or Grupomanía) were originally comprised of three brothers -- Héctor (aka Banchy), Edwin, and Oscar Serrano -- and Alfred Cotto. Banchy had previously participated in bands led by Willie Berríos and Leny Pérez, while Oscar had also been in a band led by Pérez, Grupo Uno. ~ Jason Birchmeier
