It’s 41 degrees today in New York City, which isn’t really the ideal weather for a spring cleaning. Thank god for us, the Festival Outlook is all virtual. Today we spent a good deal of our post-drunken haze updating the lineup pages for a slew of the world’s festivals, from Osheaga and Bumbershoot to Van’s Warped Tour (yes, it still exists) and the Winnipeg Folk Festival. Check out all our work below:

And while we have your attention, please be sure to bookmark Festival Outlook and follow us on Twitter. That way, you’ll get more timely updates! And if you see something missing from one of the thousand pages listed on Festival Outlook, please drop us a line and we’ll fix it asap. Of course, tips are also welcome!
