It was followed by the studio album Mirrors (1979). For Mirrors , instead of working with previous producers Sandy Pearlman (who instead went on to manage Black Sabbath) and Murray Krugman, Blue Öyster Cult chose Tom Werman , who had worked with acts such as Cheap Trick and Ted Nugent . It featured the band’s glossiest production to date. It also gave Roeser, the lead vocalist on the band’s biggest hits, bigger prominence as a vocalist, singing lead on four of the nine songs. However, the resulting album sales were disappointing.
