"One shade the more, one ray the less / Had half impaired the nameless grace / Which waves in every raven tress / and lightens her steps in each tight space." - by Lord Byron, for Roxana. What is the melody / song they dance on?
Renato Vieira Barreto It's a little difficult to find information about any artist and their tours. Sebastian's and Roxanna's web pages seem to be dormant (not up to date), so the only possibility is to get a Facebook account and start following their status updates. See facebook.com/sebastian.achaval.12 and facebook.com/roxana.suarez.315 -- Some of the the 2015 Tour information can be found from post facebook.com/sebastian.achaval.12/posts/10152699299216345
H0rsefish ...about the sitting people all over. If you ever had taken classes it's utmost important to sit whenever you can so save your precious tools, your feet, in order to use them effectively for practise (and save for later evening milonga). Maybe people in their 20's - 30's can endure long sessions, but having 9 cm high heels for hours ... good for you if you are a trained dance instructor or ballerina but for rest of the mortals ...
