Old Nine Inch Nails or Tool. What? Don't look at me like that.
You want me to be serious? Ok.
There's a guitarist out of Austin named Ian Moore. His songwriting, singing, and guitar work are very...they have an impact on you...they make you want to fuck someone, alright? And not fuck, like screw some bimbo slut for 30 minutes, no. They make you want to make love to an amazing woman for three hours and bathe in her come and collide and explode together.
If you can't get your hands on some Ian Moore, some Ben Harper or latter-day Gomez. If she's indie/arthouse, Modest Mouse. If she makes you listen to Centromatic, she's either too pretentious to achieve orgasm or that's her way of telling you she's a lesbian. Be nice about it, but steal her Portishead CD's on the way out.
