Back before the internet, one way to find new music was to go to the library and borrow tapes. Then you copy them. This is how I first heard Robin Trower. I have always felt a bit ashamed of liking Trower, because he was a bit hippy and cosmic. That was a bit uncool growing up after punk. But I really like his guitar sound. He is really gritty blues, so I am not sure what my younger self was worried about. I was reminded of my repression of my love for the music of Trower when a track was played on one of the freakzones on radio 6.
On a more modern front I really like the curtains of night
a female death metal band from the US. They don't want to be friend on myspace. Perhaps I scare them. or perhaps they think I will compare them to babes in Toyland.
