The best night to Barcelona was a Bach Concert by Schiff at the Catalan Music Palace. It is suggested that you buy tickets (online credit card payment) and print out paper tickets in advance on the official website of the concert hall, and then you can sweep the code and enter the concert hall! Very convenient! Tickets for Catalonia Music Palace are very cheap. The most expensive ticket price is only 60 euros. On the contrary, in Shanghai, the 60 euros ticket price can only sit in the last row of the first floor. If a great musician like Schiff, tickets are very difficult to grab, plus scalper fried, it may be nearly 100 euros. Besides, the interior of the concert hall is also very stunning. It is the work of Gaudi's competitor, Montanell. It can hear high-quality concerts and visit world-class buildings at the same time. Tips: The Catalan Music Palace has concerts almost every day. If you want to listen to a relaxed and happy concert, you can choose Flamingo Dance or Spanish Guitar. It's easy to understand. But if you know something about serious music, you've heard concerts in China, or your children are learning musical instruments, it's better to buy a concert ticket for a top musician like me. There are many good concerts in the season of 2018-19 (there are two Dudamel clubs at the end of September). If you go to the official website and choose one, you will get more than others on this journey!
