Now ask me to name 5 iconic singers/bands from any subsequent decade and I will struggle
That is hard - but most influential for me probably was (just thinking about it)
1) Billy Joel and his songs and incredible songwriting when I was growing up...
2) Pink Floyd - The Wall... in college
3) Genesis - The Genesis album...
4) Oingo Boingo - best concerts and great songs...
Gotta think more about others...
