As per longstanding tradition, here is a Google Calendar of all the bands playing Hopscotch, including everyone on all of the day parties. Note that this info was pulled from the Hopscotch website this past weekend, so if there are inaccuracies (especially with the day parties), please let me know. I’ll make another pass through everything next Tuesday.
You should be able to subscribe to this calendar in GCal by doing Other Calendars | Add by URL. If you want, you can then customize your own schedule by doing “add to my calendar” for those events you’re interested in.
