Grand Am

(1990)
Logo: We see a view of a mountainous road. The sky is dark blue, with various pink and yellow clouds moving fastly through the process. A car passes by through the road as thunder starts striking the road, one of them even getting too close of the car, without destroying it. The thunder then starts forming the text "GRAND AM", in a yellow metallic font, and stops coming out of the sky. "PRESENTS" then appears below.

Technique: The moving sky, the thunder striking the road.

Music/Sounds: An ominous phasing synth, with the sounds of the car, thunder, and a swoosh.

Availability: Extremely rare. Seen on the horror film Evil Spirits.

Legacy: The overly trippy and disorienting nature, along with the synth music and thunder, perhaps makes one of the most psychedelic logos we've seen so far. It may depend on your point of view however, since you could also call it as a really cheesy logo.
