One of Boston's biggest hits is a pretty good song they still play on the radio a bunch. It discusses how the feelings of one can be something "More than a Feeling" with great guitar and rums and amazing vocal harmonies.
"Don't Look Back" is another hit of Boston's also still played a lot on rock stations today. Just an all around great rock song. It's cool to see how much fun the audience is having to them playing the tune with Boston's typical intricate vocal harmonies.
It's pretty great that you can find full concerts of artists on youtube. You get to study stage present and how the visual stimuli can enhance and give you another appreciation for the underlying tunes.
"A Man I'll Never Be" sounds like typical Boston but a little slower.
"Foreplay/longtime" is a pretty cool song. It starts with an interesting piano focused rock for about a minute, then it transform into a more typical rock song with catchy lyrics discussing time and the nature of change.
"Smokin'" is another hit with a cool early vocals and tight instrumentals.
"Peace of Mind" is one of my favorite Boston songs, it's also a hit. It discusses the nature of live and incentives and how it's nice to have peace of mind.
