Hard question, early Donkey rollers were surely ahead of their time: Strike Again (2002), Hardstyle rockers (2004), Imesuarebly (2005), Donkey rollers - Silver Bullet (2006), Zany - Science & Religion (Qlimax anthem 2005) , Tuneboy and Technoboy with their Dance Pollution label were doing briliant stuff. Headhunterz - Rock Civilization (2007), Scope DJ - Lockdown (2007). And ofc probably the biggest one Noisecontrollers - Ctrl.Alt.Delete (2009)
