These are two of my favorite albums but I can imagine those new to jazz thinking Giant Steps is too intense. Although not as intense as Coltrane's Interstellar Space...
Miles Davis "Jazz at the Plaza" is pretty much the band from Kind of Blue, live. It's a good record.
There's another Miles record that is very meditative, "In a Silent Way" but it's quite different. Electric pianos and organ and John McLaughlin on guitar.
