Los Mac's, formed in Valparaíso, Chile, in 1962 by brothers David and Carlos Mac-Iver, are pioneers of Chilean rock. Initially a cover band, they evolved to create original music influenced by The Beatles, The Rolling Stones, and Bob Dylan. Their 1967 album, "Kaleidoscope Men," is a landmark in Latin American psychedelic rock, featuring the classic track "La Muerte de mi Hermano." After disbanding in 1969, they reunited in 2010, continuing to inspire with their innovative sound. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Los_Mac%27s?utm_source=openai))
