Mötley Crüe is an American heavy metal band formed in Los Angeles, California, in 1981. The group was founded by bassist Nikki Sixx, drummer Tommy Lee, singer Vince Neil and guitarist Mick Mars. Mötley Crüe has sold 100 million albums worldwide, making them one of the best-selling bands of all time. They have also achieved seven platinum or multi-platinum certifications, nine Top 10 albums on the Billboard 200 chart (including 1989's Dr. Feelgood, which is Mötley Crüe's only album to reach number one), twenty-two Top 40 mainstream rock hits, and six Top 20 pop singles. The band had experienced several short term lineup changes in the 1990s and 2000s that included vocalist John Corabi (who was Neil's replacement from 1992 to 1996) and drummers Randy Castillo and Samantha Maloney, both of whom filled in for Lee during his split from the band from 1999 to 2004.
