Boston was arguably the last great rock band of the 70's. Their debut album exploded on the scene, and it seemed there was no stopping them. Same with the second album. Sold out concerts, top of the world, then.... nothing, for nearly 20 years. But back to the album. Every song is an instant classic. Is it polished? Sure. Commercial? Maybe. Even slick in places. But immaculately executed, and regardless of all this, whose to say "commercial=bad?". Solid musicianship, great vocals, excellent pop/rock songs. What else do you want?
