How does Lester Bangs use imagery in Psychotic Reactions and Carburetor Dung?

Imagery:

"It wasn't until much later, drowning in the kitschvats of Elton John and James Taylor that I finally came to realize that grossness was the truest criterion for rock 'n' roll, the cruder the clang and grind the more fun and longer listened-to the album'd be."

"So perhaps the truest autobiography I could ever write, and I know this holds as well for many other people, would take place largely at record counters, jukeboxes, pushing forward in the driver's seat while AM walloped you on, alone under headphones with vast scenic bridges and angelic choirs in the brain through insomniac postmidnights, or just to sit at leisure stoned or not in the vast benign lap of America, slapping on sides and feeling good."
