This is not soundtrack related, but if you want to get into some older 70/80's music (rock if I had to classify them), you could look into the waterboys and crack the sky. The Waterboys are fairly mainstream and those living on the other side of the pond in the UK, Ireland and Scotland may already be familiar with them, especially if you are a tad older. I think they are pretty great myself and they are AMAZING live. Crack the Sky on the other hand, is sort of a microfamous band that is fairly local to the Baltimore region in Maryland. They really could have made it big, but due to political games and their shitty manager and their own moral agendas, they just never really hit it big, but they did open for big names such as: Styx, Supertramp, Rush, Foreigner, Electric Light Orchestra, Yes, ZZ Top, Kansas, Frank Zappa, and Boston. You can pick up both of these bands records for $5 or less fairly easily. I will attach a link to a couple youtube videos in a bit to each of their better songs, but I can't do that right now since I am on my work computer and they have that site blocked, but give me a bit and I'll do it on my phone.

Oh and to those who follow me on instagram I have some clips of the waterboys on there from a concert.
