Me and the Devil Blues. Scanlations ended right before volume 2 ended because it got licensed, but check them out. Everything about this comic is top notch. A story about Robert Johnson shouldn't have this kind of over-the-top suspense and "magic" to it, it's just amazing. It's rare when a comic sends shivers down my spine constantly like this does. The North American editions don't have the color pages, but they're well worth the money.

To branch off some of your favourites, check out stuff by the same authors if you haven't. Kiichi!, Boku to Issho, Himizu, MONSTER and PLUTO instantly come to mind. As for other authors, I'll just name names off the top of my head:

Hitoshi Iwaaki (Parasyte/Kiseijuu, Historie)
Iou Kuroda (Japan Tengu Party Illustrated, Nasu, Sexy Voice and Robo)
Makoto Isshiki (Piano no Mori, Hanada Shounen-shi)
Shinkichi Kato (National Quiz, Baka & Gogh, Ranman)
Inio Asano (Nijigahara Holograph, Solanin, Goodnight Punpun, What a Wonderful World!)
Taiyo Matsumoto (Black and White/Tekkon Kinkreet, Hanaotoko, No.5)
Daisuke Igarashi (Children of the Sea, Witches, Hanashippanashi)
Nihonbashi Yoko (G Senjou Heaven's Door, Shoujo Fight)
Makoto Yukimura (Planetes, Vinland Saga)
Ryuichi Ikegami (SANCTUARY is fabulous, STRAIN was alright... a lot of his other stuff wasn't all that great...)
Kiba Koichi (KILICO)
Fuyumi Soryo (Eternal Sabbath, Cesare. MARS is the only shoujo manga I got really gay for.)

If you wanna keep things simple, just look at what Mangascreener and Kotonoha have to offer. You really can't go wrong. All the one-shots they've done are really good too.
