One of my favorite genres of music is Blues Rock.

Blues rock is a musical genre combining bluesy improvisation over the twelve-bar blues and extended boogie jams with rock and roll styles. The core of the blues rock sound is created by the bass guitar, piano, drum kit and very importantly the electric guitar, with the electric guitar usually amplified through a tube guitar amplifier, giving it an overdriven character.

This is the direct definition of blues rock, courteous of Wikipedia, which well describes the technical side of the genre.  Only a few contemporary bands such as The White Stripes and the Black Keys have mastered the style. Pioneers in this genre include Stevie Ray Vaugh and B.B. King. In fact B.B. King is considered the King of Blues for his musical influence. He has worked with major names like U2 and even came out with an album with Eric Clapton. King started by playing for his church. He gained the nickname Blues Boy early in his career. Later that was shortened to just B. B. One of the things King excels at is his guitar solos. He ‘sings’ with his guitar. That is where the improvisation comes in. While some guitarist play patterns. B.B. King felt like the music was more of a conversation. The vocals were like a question and the guitar was an answer. Where one stops the other takes over. That’s really the core of the blues, feeling in every part of the music.
