Eva Cassidy most certainly did cut at least one LP. I own a copy but can’t tell you the title because I’m away on vacation. As for Chet Baker, look for him on any West Coast jazz album, e.g., Riverside, or with Mulligan, Konitz, Pepper, etc. I personally don’t care for his singing. You’ve gotta develop these tastes for yourself. None of us can tell you what albums by what performers you will like best.
