Blackhawk in Tenderloin

Though I'm not fond of "BeyondChron" for it's sometimes ultra-left politics, and claiming to operate a forum, though it refuses to acknowledge diverse opinions (it's essentially a Fox News on the other side of the fence), I give them credit for bringing up a bit of history I didn't know about the entire time I lived in the neighborhood. ...although I did know that the area was "uptown" once, and what are now "adult theaters" were then popular theaters. Source notes follow...
==============
222 Club, 222 Hyde St (at Turk St) In the 50s and 60s this used to be a famous jazz club called the Blackhawk. Today it is a cutting edge underground venue with DJs and live music. The Blackhawk was actually at 200 Hyde St, which is now a parking lot. (WikiTravel)
===============
From the start, the Blackhawk presented all the jazz stars, local and national, and until the Jazz Workshop opened in 1956 (with former Blackhawk regular, pianist Jeannie Hoffman). The small, ugly, 'Hawk was the Bay Area's principal modern jazz club outside the Filmore District.

Dave Brubeck, Cal Tjader, Vince Guaraldi, Vernon Alley, Art Tatum, Johnny Hodges (with John Coltrane), Anita O'Day, Oscar Peterson, the MJQ, Chico Hamilton, Red Norvo with Charles Mingus, Gerry Mulligan, Chet Barker, Miles Davis, Shelly Manne, Thelonious Monk, all played (and many recorded) there.

===================
The New York Times recently described how American Beauty was the quintessential Grateful Dead album. That album was recorded across the street from the Blackhawk at the Hyde Street Studios.

So was every Creedence Clearwater Revival album after Green River, and Santana’s legendary Abraxis. Keith Richards recorded there, along with stars too numerous to name. BeyondChron

Well, above paragraphs have named a lot of them, but thanks to BeyondChron for pointing out this landmark -- which is actually now a parking lot, in spite of 222 claims to be the reincarnation)
