I listen some long mixes of progressive psytrance (psychedelic trance), especially in Zone mode ; it let me stay on the rhythm ascending AND get me zen & cool I recommand you !
Some artists in this category I recommand a lot :
• DRURY NEVIL - FREAKS OF THE DARK
• Phatmatix
• Brain Driver (Lume)
• Khopat (Re-Activate <3)
• Rev (Bilateral dysfunction)
• Pirated Machines (pirated mind)
• Psywalker (chemical trance)
• Atomic Pulse
...
I think this type of music corresponds PERFECTLY to wipeout HD !!! you MUST try for an absolutely amazing experience in flow !
• KRAFTWERK is excellent mixed with Wipeout world !
For tournaments and unique race, I'm listening more darktrance and techno industrial music...Then when you beat your AG opponents in a big explosion, you get high on hardcore muzik !
• X-Fusion
• Noisuf-X
• Alien Vampires
• Groupe T
• Angoria
...
But not too much hardcore too, because too disturbing to rest concentrated and cool in bends Oo ! Use with moderation ^^
(Sorry if my english is poor, I'm french ^^)
But definetively electronic music. Experimental...Ambient : why not try ? IDM...Breakcore...Trance, psy...GOA...Industrial
