For me it all started in the 60s... Beatles, Dylan, Phil Ochs, Simon & Garfunkel (thanks to elder sister). Marvin Gaye, Tammi Terrell, Wonder, etc. (thanks to a close friend) Then came Joni Mitchell who inspired me to learn to play the acoustic guitar. Puccini (Mme. Butterfly), got me interested in joining a choral group in high school. College years, I first appreciated Beethoven, Chopin, etc. Then musical theatre, (transcribed for the guitar) esp. West Side Story, Carousel, Hair, Jesus Christ Superstar, just to name a few. I spent a heck of a lotta $$$ @ the store on sheet music. But it was worth it. Ancient music (e.g., Renaissance music--John Dowland, especially, and mediæval troubadour music) Then, my very favorite band...Led Zeppelin, so many facets in their music! as we all know. I got into them later in life. Oh but I always loved their biggies when they first came out (Stairway to Heaven, Goin' To California and Kashmir) Nowadays I can't stop listening to solo works by its members, especially Midnight Moonlight (The Firm) and Sister Rosetta Goes Before Us (Robert Plant & Alison Krauss.)
