Not New Orleans, but Fresno, California. San Lyon has only been hitting the music festival circuit for a couple of years, but their bright delivery of manouche jazz immediately captivated audiences. I had the privilege of hearing them for several sets at the Fresno festival last weekend. Their lead singer was missing, having scored an acting gig in New York. Hopefully, she will be back soon; or hopefully, her dream of hitting it big as an actress will come true.

Restricted 3-body problem predicted Trojan asteroids
The restricted 3-body problem simplifies the issue to one body that is massless, and all three are in a plane. The two bodies with mass orbit each other. In the rotating frame of reference where the two finite-mass bodies are stationary, there are 5 points on the plane where the third body can remain motionless. Depending on the ratio of the masses, these points are either unstable or stable to small perturbations. The sun and Jupiter fit the ratio where two of the points are stable. The existence of the Trojan asteroids was predicted 134 years before they were actually found.
