While virtually all the songs in the shows were familiar and many were familiar from progressive rock radio airplay, few of them sounded similar to their original versions. Driven by Levon Helm's syncopated, contrapuntal drumming, Dylan's songs (exemplified by a Jimi Hendrix-influenced take on "All Along the Watchtower") were re-arranged and sung with a ferocity not found on the originals, while Garth Hudson's experiments with the Lowery String Symphonizer (an early synthesizer embedded in the Lowery H25-3 organ that was adapted from the Freeman String Symphonizer) further enriched The Band's timbral palette.
