Playing warm-up sets can be as much fun as playing peak-time... Actually, most of the techno I like listening to is funky melodic warm-up material. Labels like Bio, SuperBra or Kanzleramt have many releases that fit this description and there are a few great teasers among tracks by producers such as Vince Watson, Funk D'Void, The Youngsters, John Tejada, John Thomas, Fabrice Lig (aka Soul Designer), Pascal FEOS (his "Self reflexion" album 4 example), Alexander Kowalski ("Belo Horizonte" or "Scarpia", also some of his Double X collabs), Steve Rachmad, Dave Ellesmere, Dennis DeSantis and the like... Electro can be good for warm-up sets too, you can play with those broken beats before you introduce that almighty 4/4 kick drum :)
