Wordpress Theme similar to Matrix - Event Guest List


I’m looking for a Wordpress theme similar to Matrix - Event guest list:

It seems that the author hasnt updated in over a year and a lot of complaints about incompatibility.

Looking for a theme very very simple events theme with the ability to show multiple events and pages. Ideally boxed, fixed width.

Already searched for themes tagged as event/tickets but nothing comes as close to Matrix Theme. Maybe another category with similar themes?
