I started getting into comix in the late 70's, Robert Crumb (still a fave), Robert Armstrong (Mickey Rat), Freak Brothers and all of the other drug inspired artwork from the late 60's.
Then in the 80's another wave of underground comix came around with artists like Peter Bagge, John Holmstrom, Daniel Clowes, Hernandez Brothers and Charles Burns, all of which i would highly recommend.
Peter Bagge did Hate, Neat Stuff and many other things as well as cover art for some very cool records like the Trogg Tribute LP an A Bone single and many others that i can't think of at the moment....
John Holmstrom did comix for Punk zine and many others.
Daniel Clowes has done Eightball, Lloyd Llewellyn, Ghost World (it became a movie) as well as lots of record covers like Supersuckers The Smoke Of Hell.
Hernandez Brothers did the highly influential Love and Rockets comix which raised the bar for underground comix when it came out in the early 80's. It lasted for 50 issues, lots of references to the early west coast punk scene and the stories are VERY well written.
Charles Burns has done Black Hole (which you mentioned), Dogboy (which has appeared in many comic compilations) El Borbah (again appeared in compilations) as well as many record covers....
Of the above artists, Peter Bagge is a really good place to start. Hate was a serial about a loser named Buddy Bradley (we can all see some of ourselves in this character) who goes through lifes trials and tribulations, trying to avoid the mainstream and at one point even owns a used book and record store. The stories are extremely realistic and very well written and a joy to read over and over again.
I used to be heavily into underground comix when i had more spare cash, but now it all goes into records and CD's , so i don't know a lot about the current crop of comix. But most of the stuff i've mentioned is available in better comic stores....if you want more info, give me a shout, i've gone on way too long...
