Some bands that grow into success after several albums; Journey, Yes, ZZ Top, Def Leppard to name a few, but many break big right out of the gate, like The Doors, Bad Company, and Guns N' Roses. Instant success breeds great expectations and plenty of groups fall short on meeting them on subsequent releases.  

Boston's self titled 1976 release was one of the most successful debut albums in history.  Their second, released on this day in 1978 proved Tom Scholz's band would avoid a sophomore slump.  By the end of August, Don't Look Back was closing in on having sold 5 million copies.  

But after Don't Look Back, Boston fans were left with little to look forward to. 8 years would pass before the group's third album got released. Only Scholz and Brad Delp remained from the original lineup.  The hit Amanda propelled sales of it to 4 million, but the album came nowhere close to replicating the depth of quality songs the first and second albums contained.
