I remember reading a review of their band which said one of their goals was “to start a revolution.” Had a few bright spots (If You Leave Me Now) but now the only place you hear them is background music at dollar stores. No loss.
In “Baby what a big surprise,” it’s never explained what the “big surprise” is or was.
Try their early albums with the late Terry Kath...tracks like “Questions 67 and 68”, “Make Me Smile” (radio edit, not the single) and “Dialogues Parts I and II”. Very different from their later pop-grade work.
