Two years after they recorded Friday Night in San Francisco, John McLaughlin, Al di Meola and Paco de Lucía reunited for another set of acoustic guitar trios, Passion, Grace and Fire, If this can be considered a guitar "battle" (some of the playing is ferocious and these speed demons do not let up too often), then the result is a three-way tie. This guitar summit lives up to its title.

Once you’ve heard Pat Metheny you will always recognise him, no matter what company he’s in or what instrument he’s playing, be it a simple acoustic guitar or some unlikely invention of his own. Beneath it all there’s a frank, open-hearted tunefulness that keeps the music airborne. This double album, recorded at the end of a year-long tour by his Unity Band, is as polished and sophisticated as any, but moments such as the opening melody of This Belongs to You or the gradual unfolding of Born are just plain elegant. There’s a similar quality about saxophonist Chris Potter’s playing, and all four are so relaxed in each other’s company that everything flows beautifully.

Drawing on rock, salsa, and jazz, Santana recorded one imaginative, unpredictable gem after another during the 1970s. But Caravanserai is daring even by Santana's high standards. Carlos Santana was obviously very hip to jazz fusion – something the innovative guitarist provides a generous dose of on the largely instrumental Caravanserai. Whether its approach is jazz-rock or simply rock, this album is consistently inspired and quite adventurous. Full of heartfelt, introspective guitar solos, it lacks the immediacy of Santana or Abraxas. Like the type of jazz that influenced it, this pearl (which marked the beginning of keyboardist/composer Tom Coster's highly beneficial membership in the band) requires a number of listenings in order to be absorbed and fully appreciated. But make no mistake: this is one of Santana's finest accomplishments.
