At UNION, you book a room and we send an engineer who knows what they're doing. You don't need to have engineered before. You don't need to bring anyone. We've recorded artists on their first studio session and artists with ten releases; the engineer adjusts to where you're at and gets you sounding professional.
Three rooms (COSMO, BLK MAZE, LEGACY) and engineering staff trained on every genre, available 24 hours a day.
What you get: Tracking sessions (Neumann TLM 103, Universal Audio Apollo, Yamaha HS7 monitors); mixing and mastering ready for Spotify, Apple Music, SoundCloud distribution; self-directed sessions if you bring your own engineer.
Engineering tiers: Reboost Engineer $25/hr for first sessions, beginners, tracking-only, walks you through it. Advanced Engineer $30/hr for experienced artists, mixing-focused sessions, more genre-specific expertise. Engineer rate is on top of room rental rate.
Room rates: COSMO and BLK MAZE: $13/hr overnight (12am-9am), $29/hr daytime. LEGACY: $17/hr overnight, $35/hr daytime. Same rates apply for self-directed bookings.
DAWs supported: Pro Tools, Logic Pro, Ableton Live, FL Studio. WAV stems delivered after every session.
UNION Recording Studio is built for artists who want professional results without professional-tier pricing. Three acoustically designed rooms (COSMO, BLK MAZE, LEGACY), Universal Audio interfaces, Neumann microphones, and a 24/7 schedule. Overnight rates start at $13/hr, among the most affordable in Los Angeles for a fully-staffed studio.
Engineering services include music recording, mixing, mastering, studio rental, and on-site photo and video production. No experience required. Reboost engineers are trained to support first-time bookings. New to recording? Mention it when you book; we'll match you with the right person for your project.
