My son was 10 years old when we took him to his first concert to see REO Speedwagon in Indianapolis. He was already big into music then and was taking drum lessons at that time but eventually changed his choice of instrument to guitar by the time he was a teenager. At age 5 he would play theme songs from tv shows on my grandmothers piano whenever we visited. He just had an ear for music at a very young age. We never really introduced him to music or any type of music although we did listen to rock music all the time so heard it all the time at a very young age. If I had a grandchild someday, I’d hope he/she would also enjoy classic rock music.
