"Techno" is a loose term. You probably mean one of the many types of EDM. There's a good guide to the stuff
here. A tear in the open and forever today by Tiesto go for 9 and 12 minutes respectively but may not be what you're looking for. Forever today is a good, strange mix of trance, classical and music ya'd expect to hear from an epic movie. A tear in the open is more chilled out but with that good, recognisable type of beat you'd dance to at a rave.
