Firefall returned to Criteria Studios to record their second album, which was to be titled "Tropical Nights". They were joined by the Memphis Horns and Cuban percussionist Joe Lala, a member of Manassas who had played on Firefall's debut album. But after hearing the final mix, Atlantic Records decided that the album needed to be reworked. With Jim Mason producing again, Firefall worked on the album that was renamed "Luna Sea", a pun on "lunacy", and released in July 1977. The album peaked at No. 27 on the "Billboard" magazine album chart and was certified gold two months after its release. The single "Just Remember I Love You", with backing vocals by Timothy B. Schmit, reached No. 11 on the "Billboard" Hot 100 singles chart.
