OhGeesy at Marquee Nightclub — Monday, July 13, 2026 (Cosmoprof Week)
July 13, 2026
Marquee Nightclub at The Cosmopolitan
1,500+ estimated attendees
OhGeesy performs at Marquee Nightclub at The Cosmopolitan of Las Vegas on Monday, July 13, 2026, as part of the venue's Marquee Mondays residency series — the opening night of the Cosmoprof North America 2026 trade show week at Mandalay Bay. Alejandro Coranza — who performs as OhGeesy — is a Los Angeles-based rapper and founding member of Shoreline Mafia, the Boyle Heights collective that emerged in 2016 and built a West Coast following through SoundCloud-distributed mixtapes before signing to Atlantic Records. His catalog with the group — including 'Musty,' 'Bottle Service,' and the 'ShorelineDoThatShit' series — and his solo projects since 2021 position him within the LA trap and gangster rap aesthetic that draws heavily from the Boyle Heights and East LA street music tradition. OhGeesy's Las Vegas nightclub appearances follow the pattern of West Coast hip-hop live performances: vocal performance over DJ-driven beats from his catalog, crowd energy management across a 45–75 minute set, and the specific nightclub intimacy that a performer of his profile creates in a 3,000-person room where most attendees have been streaming his music for years. His Marquee Mondays booking on July 13 is the lightest crowd night of the CPNA week — Monday at Marquee operates at lower density than Friday or Saturday, with easier guest list access and a crowd that skews toward industry professionals (in this case beauty industry attendees from Cosmoprof) and Las Vegas regulars who specifically choose Monday as their night out. Marquee Nightclub at The Cosmopolitan of Las Vegas is at 3708 S Las Vegas Blvd. Doors open at 10:30 PM. Guest list through NoCoverVegas covers general admission for qualifying groups; Monday is among the easiest nights of the week for guest list approval at Marquee.

Frequently Asked Questions
- Is Monday a good night to go out in Las Vegas during Cosmoprof week?
- Monday is a reliable nightclub night during convention weeks in Las Vegas — the crowd is smaller than Friday or Saturday, which means lower door pressure, easier guest list access, and a more relaxed nightclub environment. During Cosmoprof North America week, Monday July 13 is Day 1 of the show floor, meaning many beauty industry attendees arrive Sunday and are ready to go out Monday evening after the convention opening. The professional demographic (beauty buyers, salon owners, brand founders) tends to be fashion-forward and accustomed to nightlife — making CPNA-week Mondays at Marquee more energetic than a typical off-season Monday. Guest list through NoCoverVegas is available with same-day or next-day registration for Monday nights.
- What is Shoreline Mafia and why does OhGeesy perform solo in Las Vegas?
- Shoreline Mafia is a four-member LA rap collective from Boyle Heights — OhGeesy, Rob Vicious, Fenix Flexin, and Master Kato — who built an organic West Coast following through SoundCloud before signing to Atlantic Records. OhGeesy has pursued a parallel solo career since 2021 alongside his Shoreline Mafia work, releasing solo projects that expand on the LA trap and gangster rap aesthetic of the group's collective output. His Las Vegas appearances as a solo act draw from both his solo catalog and his Shoreline Mafia catalog — the tracks that made him recognizable nationally — in a live performance format typical of his West Coast rap peer group. The NoCoverVegas guest list covers his Marquee appearance for qualifying groups.
