L4 is an indie pop/rock band from the Gràcia neighborhood of Barcelona. Formed by six young musicians aged between 20 and 25 (born 2000–2005), the band met at a music school and has since developed its own style, influenced by classic bands like The Cure and Oasis, as well as modern artists such as The Backseat Lovers and Noah Kahan.

The band’s name refers to Line 4 of the Barcelona metro, which all six members share.

L4 has released four singles on digital platforms such as Spotify and Apple Music. Their debut single, “Coffee Shop” (September 2024), served as their introduction — a nostalgic and summery tune.
Their second release, “6 Tracks From Home” (November 2024), takes on a darker, rock-inspired tone, showing their more urban side and linking back to the band’s name.

In May 2025, they released “Birthday Wishes”, a sensitive and visual track with a message that resonates universally. Their fourth single, “Dreamer”, talks about chasing dreams even when they feel out of reach.

In November 2025, L4 will release their debut album “The Woods”, featuring ten songs including all four singles.

All songs are written by lead singer Alba Planas and self-produced by guitarist Marc Fernández.

Upcoming shows include Sala Heliogàbal on November 7th and Diobar later that month.

Some of their most notable performances include the DmJ competition at La Fontana, the Marató concert on Carrer Gran de Gràcia, Petit Mercat de Mercats in Barcelona, Festival Aparador in Calonge, Sala Freedonia in the Raval neighborhood, and various local festivals.
