Rock and Roll is my favorite music genre, are you familiar with it?
I love Rock!  it is a popular music that originated and evolved in the United States during the late 1940s
Yes rock and roll evolved from from African American musical styles such as gospel, blues, jazz, boogie woogie,along with country music.
It did! And classic rock and roll is usually played with one or two electric guitars. but now we usually add a bass to the group.
