Ty Segall is the enthusiastic kid brother of San Francisco's venerable garage-rock scene. "Pretty Baby (You're So Ugly)” and "Drop Dead Baby" are snotty and defiantly raw, but they also drip with boyish joy. Whether reaching new levels of twin-guitar intensity on "Doctor Doctor" or indulging in some Jimmy Page cosplaying with "Rat Race," you can hear his mile-wide grin behind every fuzzy note.
