Okay I'm on shaky ground here...for a start I presume that, with the names I've given above, I've already given a pretty vague idea of what I'm after (since they cover a few genres). Plus, I only know the go-to artists, so I'm no expert...but it just seems to me there's a certain soulful jazziness that plays through these three that I really like...and I wondered if anyone knew what I might enjoy further.
