Multi Day Events below list of today Events not working properly

We have event calendar a site where users can post cultural events. On a day there can be up to 50 events. But a large part of these events are events like exhibitions that started months ago. If you show events in the list that are still active, but started days or months ago, the top of the list will show these events first. One has to scroll down to find the concerts, theater, parties etc. that actually are only today. One could filter the events that started before today, but then a site visitor doesn't know which exhibitions are running.

How can I create a list of today-events and beneath that a list of running events? I was thinking of inserting a module in the template (with loadmodule), but the events module has no option to show <em>only</em> past / running events.
