Spanish pop duo Estopa, formed by brothers José and David Muñoz, made an impressive debut with their self-titled album in 2001, released by BMG-Ariola. Playing a mixture of flamenco-pop and rhumba-rock, Estopa became a top-selling act in less than a year; they were voted Revelation of the Year and Best Spanish Band at the 2000 Amigo Awards. In 2001, they released Destrangis and in 2004 the smash hit ¿La Calle Es Tuya?, which followed a cameo appearance on Antonio Mercero's film The 4th Floor. The duo's subsequent albums of the 2000s (2005's Voces de Ultrarumba, 2008's Allenrok, and 2009's X Anniversarivm) didn't quite match the success or sales of their first record, but December 2011's 2.0 saw a return to past glories -- ironically with an update and evolution of their rumba-rock sound. It hit number one, and remained on the charts for all of 2012. Esto Es Estopa, released in 2014 in audio and video packages, debuted at number one in Spain and spent several months within the Top Ten -- plus high chart appearances in Italy and Mexico. Not disappointing their fans in the slightest, the Muñoz brothers returned in 2015 with Rumba a lo Desconocido. ~ Drago Bonacich
