Penthouse’s first full-length album, **Balcony**, was released digitally on 22 March 2023 and issued on CD on 29 March 2023; the album collected the band’s early streaming-era material into a 10-track set and marked their first physical release, making it an important milestone in the group’s history. The record presents the duo-vocal-led Penthouse sound in a polished pop format, with jazz and R&B influences and a city-pop-adjacent atmosphere, and it includes several songs that had already appeared as digital singles before the album, such as “恋標 / Signpost,” “流星群 / Shooting Star,” “雨宿り / Umbrella,” “閃光花 / Sparklers,” and “Take Me Maybe.” The first-limited CD edition also included a bonus DVD featuring footage from a 2022 live performance, adding collector value and reinforcing the album’s role as a summary of the band’s early rise.
