"I love springtime in the city - there was a concert in the park yesterday and tonight there's a block party in the art district."

"Люблю весну в городе - вчера в парке был концерт, а сегодня в квартале художников устраивается благотворительная вечеринка (благотворительный вечер) под открытым небом".
Ули, у нас нет в России block parties, в словаре перевод "благотворительная вечеринка". Верно?
Art district - как думаешь, правильно перевела?

Art district you nailed. It's the part of town where all the galleries are. However, a block party isn't necessarily charitable (in fact, I've never been to one that was). Usually it's just a chance for the neighbors to interact socially. It usually takes place on a cul de sac, since there's less through traffic. It can be on the occasion of a birthday, a birth, an engagement, etc. or to raise money informally for a neighbor who experienced a loss or financial setback. In an art district, it would mean that all the galleries put tables outside with wine and cheese, etc. for passersby to enjoy as they visit all the galleries. So I guess the best thing to call it in Russian would be something like a "street party," if such a thing were possible.

Наверное, "народные гуляния" подойдут. "Люблю весну в городе - вчера в парке был концерт, а сегодня в квартале художников устраиваются народные гуляния"
