From the bonanza department of free music that ain't bad because sound is the heart of your blood, and your head is made of blood, with sponsorship from the Center of the Study of the Affects of Relayed Information comes:

Seastones, a live side project of Grateful Dead bassist Phil Lesh. For a period of time in the early to mid 70's, it seems the Dead would stop the pseudo-country jamboree noodlefests, and play (with the aid of this 'Ned Lagin' character) some improv noise grooves bordering on properly non-narrative soundscapes. Now, I'm no deadhead, but if you cull through your Internet Archive for 'Seastones,' and you go directly to those tracks called 'Seastones' from some of the Dead shows that the search yields, you are sure to find some fantastic time spending audio from the depths of. It's a real relic-totem in the scope of man's love of tools and music technology, and a footnote in how smart dudes have crazy instrument collections. I think this is the kind of stuff gave the Dead, the real 'psychedelic cred,' or at least sustained it, after the merry pranksters were only a memory. Believe it, or be set aside!  ¶ 12:48 PM
