Jeffrey Gaines could easily see himself living in the 1960s, hanging out and making music at someplace like Haight-Asbury in San Francisco. On the phone, he sounds mellow and laid back. He peppers his speech with "dude" and "vibe." And he's a singer-songwriter, for crying out loud. This is the '90s. If you're a guy, you gotta play alternative or swing or hip-hop, or you're just not happening. Gaines doesn't listen to that kind of talk. By the mid-'80s, he caught his first break. WTPA-FM (93.5) in Mechanicsburg was putting out a CD featuring local musicians.
