One of the their earliest shows at Winterland, 22nd October 1967, clearly shows the band venturing well beyond the snappy, dance-oriented music they had been playing during the previous year. Garcia''s slicing guitar leads were rapidly developing and the group was now propelled by a rhythm section featuring the double drummers. Although the core primal sound is still very much intact, the Grateful Dead were now developing a new sound, ripe with possibilities, a new instalment of Grateful Dead history is here provided for Dead Heads across the world to share this incredible concert on CD.
