I saw Avishai Cohen performing this piece above live recently. He is a great jazz improviser on the double base. Enjoy!

Hey, I’m a fan also! Discovered him recently. I think for me it is the fact that he evidently listened to the same music that I did, growing up. He then moved in a similar trajectory (classical, Jazz, Latin music), though of course he actually creates something out of all of that. I mostly like his faster pieces, with all the time signatures games he likes to play. Anyhow, I envy you…
Also, a cleaner version of “Remembering”
This is from his Blue Note concert. From the same concert, another piece with the aforementioned time signature shifts
Hi Moshe:
I also discovered him recently. Thanks to Pandora. It is a really useful way to learn about new music.
No Pandora in Canada, which is the start of a really long rant (about everything else that’s not available in Canada) that I will spare you…
Hi David
Sorry off topic…I checked your short review paper today regarding AdS/CFT.
Can I ask a general question regarding AdS/CFT and its relation to String compactifications?
What is the nature of the CFT duals of AdS string vacua emerging for example in compactifications like
KKLT? Intuitively some short of correspondence should hold for such vacua too and thus they should have CFT duals but how can we be sure that they really exist? If they don’t what exactly this tell us for the correspondence and for these vacua? On the other hand do you think we could we use somehow a version of AdS/CFT to eliminate classes of vacua and reduce the landscape?
Hi Giotis:
Good questions. I have to think quite a bit about them (especially to get up to date on the latest of some of those developments). I’m still planning to write some side notes about my review paper. I might answer some of those questions then.
I checked the arxiv and this seems to be an open complex problem. There is no clear picture for the CFT duals even of Freund-Rubin compactifications with a large hierarchy between AdS and the extra space let alone KKLT. The problem for such compactifications appears to be that it is difficult to find the equivalent brane construction (with the corresponding near horizon geometry) and even more difficult to derive the low energy field theory from this construction.
But I find it odd that for the microscopic derivation of AdS/CFT this is the only practical method out there for constructing CFT duals i.e. via brane constructions following in a way the technic of the original AdS/CFT derivation (D3 branes etc). It seems too restrictive. Anyway maybe I’m missing something.
For KKLT specifically I found hep-th/0308175 and references within but it is to old to be the latest development.
Off topic, but still a video
