5 Underrated 1970s Rock Albums That Deserved Bigger Sales

Even the most influential rock bands can release an album that, for one reason or another, fails to achieve the commercial success many expected. Sometimes the timing is wrong. Sometimes the sound is too experimental for the moment. In other cases, critics and casual listeners simply do not recognize the album’s strengths until years later.

The 1970s produced some of the greatest rock albums of all time, but not every strong release became a blockbuster. Some records earned loyal fan followings without reaching the sales numbers associated with the biggest names in classic rock. These underrated 1970s rock albums may not have sold as much as people expected, but they remain important, memorable, and highly respected by passionate listeners.

5. ‘Secret Treaties’ by Blue Oyster Cult

Year released: 1974

Total albums sold: 500,000

Secret Treaties was the third studio album by Blue Oyster Cult, and it remains one of the band’s most fascinating releases. The album spent 14 weeks on the U.S. album charts, but it only reached No. 53. For a record that many classic rock fans now consider one of the band’s strongest efforts, those sales figures feel surprisingly modest.

Part of what makes Secret Treaties so interesting is the creative team behind it. The band did not write the lyrics for the album, which is unusual for a rock record with such a distinct identity. Future punk poet Patti Smith contributed, along with producer Sandy Pearlman and rock critic Richard Meltzer. The result was a dark, imaginative, and ambitious album that helped define Blue Oyster Cult’s mysterious style. It may not have been a massive seller, but it remains a standout example of underrated 1970s rock.

4. ‘Get Your Wings’ by Aerosmith

Year released: 1974

Total albums sold: 3 million

Aerosmith’s second album, Get Your Wings, suffered mainly because of timing. The band’s debut album had a delayed release, which meant their follow-up arrived only about two months later. Fans had barely had time to discover the first record before another Aerosmith album was already available.

That crowded release window likely kept Get Your Wings from making the immediate impact it deserved. Over time, however, many listeners have come to view it as a major step forward for the band. Songs such as “Seasons of Whither,” “Same Old Song and Dance,” and “Lord of the Thighs” showed Aerosmith growing into the sound that would later make them one of the biggest rock acts of the decade. While 3 million copies is hardly a failure, the album still feels underrated when compared with the band’s later commercial peak.

3. ‘In Through the Out Door’ by Led Zeppelin

Year released: 1979

Total albums sold: 6 million

Led Zeppelin’s final studio album, In Through the Out Door, arrived under difficult circumstances and has often been judged more harshly than much of the band’s earlier work. The album was reportedly put together in just three weeks, which was a very short period for a group known for crafting ambitious and carefully layered rock music.

Critics were divided, and some fans were uncertain about what to expect from Led Zeppelin at the end of the 1970s. Still, the album has more to offer than its reputation sometimes suggests. The band experimented with different textures and even incorporated Latin-influenced ideas. Most notably, “Fool in the Rain” became one of the album’s defining tracks and showed that Led Zeppelin could still surprise listeners. Although it sold millions, In Through the Out Door remains underrated compared with the band’s most celebrated albums.

2. ‘Burn’ by Deep Purple

Year released: 1974

Total albums sold: 8 million

Burn, the eighth studio album by Deep Purple, came during a major period of transition for the band. The lineup changed significantly with the addition of bassist and vocalist Glenn Hughes, formerly of Trapeze. The group also brought in David Coverdale as lead vocalist, even though he was not yet a widely known name.

Those changes could have alienated longtime fans, especially because the band’s sound also shifted. Deep Purple incorporated more boogie rock and blues elements into its established hard rock style, giving Burn a different character from earlier releases. Instead of rejecting the new direction, many fans embraced it. The album reached No. 3 in the U.K. and No. 9 in the U.S., proving that the band still had strong momentum. Even so, it is often overshadowed by other Deep Purple classics and deserves more attention among essential 1970s hard rock albums.

1. ‘Don’t Look Back’ by Boston

Year released: 1978

Total albums sold: 8 million

Boston’s Don’t Look Back takes the top spot because expectations were enormous after the band’s highly successful debut album. In this case, timing was again a major factor, but for the opposite reason from Aerosmith’s Get Your Wings. Boston took more than two years to release its second album, and some impatient fans were already wondering whether the follow-up would live up to the wait.

The album ultimately delivered strong classic rock songs and polished production, including “Don’t Look Back” and “Feelin’ Satisfied.” Despite selling 8 million copies, it has often been viewed in the shadow of Boston’s debut. That comparison has made it feel less appreciated than it should be. As a standalone album, Don’t Look Back remains a powerful example of 1970s arena rock and one of the decade’s most underrated major releases.

These albums prove that sales numbers and long-term reputation do not always match. Each record had challenges, from poor timing to lineup changes to mixed critical reactions, but all five continue to matter to classic rock fans today.
