Best known for its distinctive fusion of Latin-flavored jazz, funk, rock, and soul, War was unquestionably one of the most successful fusion bands to emerge in the early '70s. Initially working with Eric Burdon, former lead singer with the British '60s band the Animals, the seven-member team enjoyed a commercial breakthrough with 1971's "All Day Music." The follow-up, The World Is a Ghetto took War mainstream thanks to the crossover success of the title track, a top 10 pop and R&B smash as 1972 became 1973. Cuts like the 13-minute-plus jazz-flavored adventure known as "City, Country, City" alongside the witty "Where Was You At" and the eerie "Four Cornered Room" were standouts on the six-track album. But it was the immediacy of the No. 2 pop single "The Cisco Kid," with its catchy hook that helped give the band a chart-topping No. 1 gold-selling album in 1973, arguably the best representation of its work as groove pioneers of the day. --David Nathan
