Hobbies and Interesting Links

I love spending my time playing the blues on the guitar, the rock 'n' roll and bluesy stuff on the piano, and singing... Below you can find some of my favorite links for two of my idols in music: Stevie Ray Vaughan and Elvis Presley. I'll always be grateful to you guys for your company...

• Stevie Ray Vaughan (Little Wing, Texas Flood, Leave My Girl Alone, May I Have A Talk With You, Love Struck Baby, Rude Mood)
• Elvis Presley (My Way, Stranger In The Crowd, If I Can Dream, Are You Lonesome Tonight? (last concert in earth), Blue Eyes Crying In The Rain*)

* Last song Elvis ever sang (in his house).
