first off mike jones was good back in tha day when he came out wit bumper kit and the others, Ballin underground has some classics. chamillion was apart of the house.......and so was flip, barely........Drank up in my cup was acually the song that got me into houston rap.........which btw is the only thing i listen to......and yes Z-Ro and Trae are very underratted..Buy the Geurilla Maab CD: Rise(Classic)...they are my favs. out of houston, not downin he others though.......groups/artists out of houston that are worth listening too: UGK,DSR, SUC, OG Ron C(everybody should have a F-Action CD), Michael Watts, sir daily & doodie(not together anymore btw but Hoggin Da Mic is a classic to me), Freestyle kingz (Off the Chain is a good CD),Boss hogg outlaws, lil Flip, and some others but as far as swishahouse goes i dont think their worth listenin to anymore considering everybody i listed too now has their own labels. DJ Screw speaks for itself, alot of history behind his name...SOUTHSIA FALIA
and btw, u should listen/find their older underground CDs....most of them u can find at sosouth.com
