Well, anyway, when/if I next listen to the Grateful Dead, I'll now know the name of the bass player; likewise when I see one of those basses on ebay.I think it is fair to have never heard of Jack Casady. I heard of him firstly through the Epiphone bass, then from his cameo on the Electric Ladyland album. Having now delved a bit deeper into Jefferson Airplane's output I would say it maybe isn't the most obvious place to go looking for genre-defining high-stakes bass performances; commercial hippy pop with a jam band edge, zany abstract and satirical lyrics stuffed dated political messages, interspersed with meandering out-of-tune guitar solos replete with that garishly wide, weird renaissance vibrato that all those West Coast guitarists adopted. Two singers fighting over the top of each other with a similar wailing vibrato.
If anything Jack can sometimes be a bit tricky to make out on the earlier material. On Somebody To Love he is playing quite a busy line, but it becomes swamped in the murk of reverb they buried the track in.
I'm a big fan of Jack actually. We have a broadly similar right-hand techniques, and I admire the fidelity and dynamics he squeezed from shortscale semi-hollow basses which, around these parts at least, tend to get typecast as toneless, ill-defined thump machines. The dichotomy within Hot Tuna is quite stark. Jack was beta testing pioneering active electronics, in a roots Americana band! Brilliant.
Having said that I can't really think of anything Casady achieved beyond about the mid 1970s. Where as Jack in the '80s and '90s? If you grew up with Bootsy, Jaco et al then Jack is just an ancient hippy bassist that lacked the rhythmic formalities of the former while matching the business, if not the harmonic complexity, of the latter. One of those '60s 'join in' bassists that clings onto the side of the hurtling mine cart of music their various band produced (Phil Lesh and John Entwistle spring to mind), rather than play in the pocket etc. While I admire Jack's playing, there isn't an awful lot of take-home content to his playing.
I did once nearly buy a CD, but I think I didn't.
