musicians who 'wear their heart on their sleeves"....

[gater]

I think most artists, not just musicians do. Steve mentioned Cohen and Young, and I would add Waits to those two. How about the way Neil Peart did with Rush after the death of his daughter, then his wife, or pretty much any Bruce album, say "The Rising" and the tune "Mary's Place", or perhaps Simon and Garfunkel's "Silent Night/ 6 O'clock News". Much of James Taylor's early stuff was a direct result of his mental health treatments when he was younger, and Bad Religion, NoFX, and Anti-Flag have not just worn their hearts on their sleeves (Black Hearts for Anti-Flag), but thrust them up in people's grills with great regularity! Even Genesis (go re-listen to "Jesus He Knows Me") have done it. Since most artists expose some part of themselves in their work, I believe pretty much any music outside the realm of "Yummy, Yummy, Yummy" by the Archies (and its ilk thru the years) has some part of the artist's heart and soul being offered up for inspection by the masses.
