Jazz Recommendations.

I echo most of the responses here already, including Ralphp's. His (presumably he) post raises a few points I would add.

Look around for jazz stations on line. I know that there is WBGO in Newark, NJ, and WMOT out of Tennessee; there's another full time one in the bay area. There's also WKCR in New York which features Phil Schaap. Though these stations tend to play a lot of more recent and local stuff (something jazz lovers can be really condescending toward), they do mix it up some. And it's free sampling when you're starting out. Also, you can catch sessions of the NPR jazz programming ("JazzSet", "Piano Jazz", "Live from Lincoln Center") on line as well. Great ways to get to know the music.

Because the radio outlets are fewer and farther between for us, you do need to be prepared to buy. Used shops, it goes without saying, are great. They also tend to be cheaper on brand new stuff, and tend only to carry the more mainline artists, good for getting one's feet wet.

As Goheelz suggested, notice the other artists backing the title artist. The greatest period of this music involved cats listenting while playing back up, and then turning it into their own thing.

As for particular titles, lately I cannot get enough of Ahamad Jamal's "Cross Country Tour." It's a two-disc set that features some of his greatest stuff, which, incidentally, proved a big inspriation for one Miles Dewey Davis. Also gotta push the following:

Rachelle Ferell, "First Instrument" - range AND control
Coltrane, "Blue Train" and of course, "Love Supreme"
Wes Montgomery, "Smokin at the Half Note"
Ellington, "Live at Newport 1956" - wanna hear a saxaphone start a riot?
Branford Marsalis, "Renaissance"

In any and all cases, good listening.

Print sources such as Down Beat or JazzTimes provide insight into the genre as well as copious reviews of current jazz releases. Both publications provide retrospectives of acknowledged jazz legends as well as links to other sites and radio stations. If the jazz neophyte's interest is piqued I would point them to books or articles written by Leonard Feather, Ira Gitler, Barry Kernfeld, Nat Hentoff and many others. As for music:

Mingus' "Ah, Um" is great fun, as is Sonny Rollins' "Way Out West"; but for pushing the envelope, try a dose of Perez Prado's "Havana 3 AM"

The more I think about it, turning on someone to jazz is more of a personal choice on the listener's part. It's like forcing someone to quit smoking, or going on a diet. Expanding your mind to something new is hard to do when you don't want to do it.

To turn someone on to jazz by getting them to start listening to jazz stations, reading books on jazz, cruising music stores to find jazz seems more work than most listeners want to do. Especially listeners that aren't into jazz in the first place. I got into jazz by getting into jazz. No one force fed it to me and I didn't find myself searching for musical truths. One day I picked up Kind of Blue because I heard so much about it and that was it. The flood gates were opened.

I am still trying to get into rap. Now, for me, that's a flood gate that's jammed and hard to push.

FYI:

I posted a thread about a Blue Note Records sale at Tower Records (25% off--no affiliation with tower) and included a list of Blue Note recordings that I think would be a welcome addition to any collection. It tends mostly towards Bop and Hard Bop, which is Blue Note's strength. Here's the thread

I would direct them to try some of the CD on this list: www.jazzwithbobparlocha.com/top40/
