I always heard great music growing up with my dad, a jazz musician, and this was always one of his favorites and I think my all-time favorite. "Blue Train" is an essential Coltrane album as well as many others. Hartman's catalog is kind of inconsistent and I don't think this recording w/Coltrane was ever matched. Hartman recorded another Impulse album about the same time with Hank Jones, Illinois Jaquet, Kenny Burrell, Jim Hall, Milt Hinton, and Elvin Jones that's pretty good-"I Just Dropped By to Say Hello"-I think it's still available (I have the LP and the CD). Clint Eastwood is a fan of Hartman's and I know he included some of his tunes in movies such as "The Bridges of Madison County". Also check out Joe Williams.
