Dave Matthews Band is amazing when you are stoned. His lyrics are so deep and powerful, not to mention the music just sounds absolutely amazing. If you arent really a fan, or havent heard him much, listen to his LIVE music. Seriously, DMB is 10000x better live. His new album, "Big Whiskey and the Groogrux King" is very very good as well. The new Cd seems more about the lryics, and a dedication to his long time friend and bandmember (and AMAZING saxophonist), Leroi Moore.
On a completely different note, Lil Wayne is awesome when you are high. I love lightin up a blunt to Weezy. Good beats, and good lyrics. His mixtapes are where his best music is, but Tha Carter II and III were both very good. The way he carries himslef and talks about himself makes him so much more of a badass to me.
Emimen is surprisingly very good when you are high too. The man is a poet more than a musician. Not someone I really enjoy listening to alot, but I just love the way he gets his message across. In his new album, "Relapse", he seriously takes you to his own world where there are no rules, and really shows you the dark side of life (listen to "Stay Wide Awake"). He is an absolute genius when it comes to his lyrics and flow. When you listen to him do think of him as a rapper, bc I truly believe the man is a poet. He is pretty hard to follow though cause he goes so fast. I love to have his lyrics up on my comp and follow along as I listen. He is a sick dark man, but the way he can you fell about the world is unreal. He seriously moves you if you follow his lyrics. Like the way Dave Matthews can make me feel so happy and good, Eminem will make you feel hatred and anger toward a cold evil world. Insane.
Techno-wise, I really like Perpetual Groove. I know they arent as techno as others, but they are really good. Songs like "Teakwood Betz" and "TSMM" are both very trippy songs to listen to when stoned I love just turning all the lights off, playing P-Groove and either setting my iTunes to the visualizer or just closing my eys and taking it all in. Their music is real instruments, which makes the music more amazing. It isnt crap made on a computer like alot of techno (which is why I dont consider P-Groove true techno, which Im not a fan of). For me, the songs all seem to have a meaning, even without lyrics, and they all make me personally feel really good and happy, as they seem to send a peaceful vibe.
Finally, Widespread Panic is really good too. Like Dave Matthews Band, they have a unique sound that is very moving. With their deep lyrics, they are sometimes hard to understand, but high or not, I just love their sound. I havent seen them live yet, but I am going to see them live with Allman Brothers, which should be absolutely amazing, seeing as they are both great jam bands from different generations.
think i'll light one up and put some oceanlab on.
