One of the more remarkable aspects of Stan Getz's 1972 masterpiece is just how organic he was able to keep the sound. The band surrounding Getz on this Columbia date was led by Chick Corea with his Return to Forever (electric) bassist Stanley Clarke, drummer Tony Williams, and Brazilian master percussionist Airto. With the exception of Clarke, all the rest had played with Miles Davis in his then-experimental electric bands. Corea's Return to Forever was just getting itself off the fusion ground, while Williams had been with John McLaughlin and Larry Young in Lifetime on top of his experience with Davis.
The Doobie Brothers' third long-player was the charm, their most substantial and consistent album to date, and one that rode the charts for a year. It was also a study in contrasts, Tom Johnston's harder-edged, bolder rocking numbers balanced by Patrick Simmons' more laid-back country-rock ballad style. The leadoff track, Johnston's "Natural Thing," melded the two, opening with interlocking guitars and showcasing the band's exquisite soaring harmonies around a beautiful melody, all wrapped up in a midtempo beat – the result was somewhere midway between Allman Brothers-style virtuosity and Eagles/Crosby & Nash-type lyricism, which defined this period in the Doobies' history and gave them a well-deserved lock on the top of the charts. Next up was the punchy, catchy "Long Train Runnin'," a piece they'd been playing for years as an instrumental – a reluctant Johnston was persuaded by producer Ted Templeman to write lyrics to it and record the song, and the resulting track became the group's next hit.
