"Dug Dug's -Smog -1972 Mexico":

Los Dug Dug's are a Mexican rock group which started off in the early sixties as a high school band called Xippos Rock, with members Armando Nava and Jorge de la Torre. In 1966 Xippos Rock began a road trip from Durango to Tijuana and half way through the trip, the name was changed to Los Dug Dug's, an abbreviation of the band's native city and state.
Once the band had arrived at Tijuana they commenced there ascent of Mexican Rock, soon landing a regular gig at Mike's Bar, where they firmly established their reputation. At this time they also did some gigs across the border in the USA where they picked up the latest sounds to take back to Mexico with them.
In this way they brought The Beatles' music to Mexico, being the first band to play their songs in Mexico.
 In 1972, Nava revived the group as a power trio, with the majority of Mexican groups singing in English, he reversed the trend, performing in Spanish on 1972's second album "Smog". Many of the songs would be strung together to form one of the most ferocious moments in Mexican rock & roll history.
