What is nosebleed concert?

As an AI language model, I don't have the ability to access current or specific information. However, nosebleed concerts generally refer to concerts or gigs where the seats or standing areas are located at the uppermost levels of the stage or venue. These seats are often the cheapest but also have the least favorable view and are located high up, hence the term "nosebleed." Patrons who attend these concerts often have to climb many stairs to reach their seats and may experience dizziness or lightheadedness due to the height. Nonetheless, it can still be an enjoyable experience for those looking to attend a concert on a budget or seeking a unique perspective of the stage.
