result, the planned record release party became the band's last public performance. They later played one more private show the following day in Robert Eggplant's backyard in Pinole, California. Reception and legacy In a retrospective review, Adam Bregman of AllMusic awarded Energy 4 out of 5 stars and considered it among the best albums of the ska punk genre. He praised the album for "succeed[ing] in combining all sorts of elements" and called it an "unsurpassed, highly intelligent, extremely fun record." In 2006, Energy was ranked as the highest rated punk album of 1989 and 6th highest rated ever on Sputnikmusic. BuzzFeed also included the album at number 12 on their list of "36 Pop Punk Albums You Need To Hear Before You F——ing Die". Many artists have covered the songs on Energy (and Hectic), including the tribute album Take Warning: The Songs of Operation Ivy. The Leftöver Crack song "Gay Rude Boys Unite" is a parody of "Unity" and the introduction music is deliberately similar to that of "Yellin' in My Ear". Split Lip's 1996 compilation album Archived Music for Stubborn People: Songs You May or May Not Have Heard Before included a cover of "Unity." Goldfinger covered the song "Smiling" on their live album Foot in Mouth. Hollywood Undead covered the song "Bad Town" on their album Desperate Measures. "Knowledge" has been covered by Green Day on their Slappy EP (later featured on the 1,039/Smoothed Out Slappy Hours collection) and Millencolin on their Skauch EP. The American punk rock band Energy named themselves after this album.
