While Coltrane would later go on to record some of the most important records in Jazz ('My Favorite Things,' 'A Love Supreme,' and 'Giant Steps' among them), this particular recording is outstanding and often overlooked. 'Blue Train' is an excellent selection for someone interested in exploring Jazz for the first time, as it is pretty accessible.
From a guitarist's perspective, 'Blue Train' may lack the emotional intensity of some of his later recordings, but it still makes for outstanding music. The playing of Coltrane, Lee Morgan on trumpet, and pianist Kenny Drew are especially good. Check them out for ideas and inspiration. Overall, the arrangements make great material for a blues guitarist looking to move into jazzier territory and a great excuse to explore lead playing outside of the typical blues scales and pentatonics.
Personally, this is one of my favorites and well worth checking out.
