Of all the American bands who aspired to the mighty metal mantle of Led Zeppelin, to my ears, none remotely approached manic nirvana as did the Stone Temple Pilots.
Though they emerged in the grunge era, there was nothing "alternative" about this quartet. Astute hard rockers to the core who knew how to ply an acoustic ballad when necessary, STP were mercurial in their melding of pop hooks with sonic riffs. Akin to John Paul Jones - STP bassist Robert Emile DeLeo is a James Jamerson disciple - purveying passages peppered with rhythm & blues, and soul.
An arranger, writer, and master motif maker, Robert utilized a wide array of instruments, spanning vintage Fender, Rickenbacker, Danelectro, and his signature Schecter Model T.
Regardless of his choice of tools, you can always identify Robert DeLeo by way of his tone, smooth articulation and harmonic prowess - which is the mark of an exemplary bassist.
