I want to find out the title/artist of a lyric-less instrumental song
it is used in Tony Robbins' infomercials and also briefly as part of
the L.A. Laker's warm-up song (at the beginning)This Lakers mix you
can find through any filesharing app.

It is keyboard melody that loops over a measure (sounds like a
newsroom bumper song), sustained power chords jump in every few
measures for drama. God bless you if you can find this elusive gem.
