Iron Maiden is one of the most influential and iconic heavy metal bands of all time. Formed in 1975 in East London by bassist and primary songwriter Steve Harris, the band is known for their fast, complex guitar riffs, theatrical live performances, and fantasy and historical-themed lyrics. They are considered pioneers of the New Wave of British Heavy Metal (NWOBHM) movement in the late 1970s and early 1980s.

Iron Maiden (1980) is their self-titled debut album, with songs like "Running Free" and "Phantom of the Opera," which helped establish them as a force in heavy metal. The Number of the Beast (1982) is their breakthrough album featured hits like "Run to the Hills" and the title track, and is considered a heavy metal classic.

Iron Maiden is also famous for its mascot, Eddie, a skeletal figure that has appeared on all of their album covers and has become a central figure in their live shows. Iron Maiden's influence on heavy metal is immense, both musically and culturally. They've sold over 100 million albums worldwide, headlined massive tours, and are revered for their commitment to creative independence and maintaining their classic sound throughout decades. Their fan base, known as the "Iron Maiden Army," is incredibly loyal, and the band continues to release new music and tour globally.
