Guitarist and songwriter Tapio Ylinen founded his record label Eclipse Music in 2007. The label soon became one of the essential publishers of contemporary jazz and progressive music in Finland. As a songwriter Tapio channels together the sensitivity of the great singer-songwriters with classic rock sounds, blues guitar and a touch of progressive rock styles.

After releasing two Finnish language rock albums (Nuoruus in 2012 and Eläimistä ja kuolemasta in 2016) Ylinen released his debut English language album Left Unsaid in 2018. The album received good reviews and was a modest commercial success and gave Ylinen confidence to compose the most ambitious work of his career.

In 2019 Ylinen brought together an all-star cast of musicians from the vibrant Helsinki jazz scene to form a jazz supergroup: Mortality. The band's debut album was released in November 2019 to great acclaim. The concept album dealing thematically with the limits of human existence was the brainchild of the group's producer Ylinen, who wrote the bulk of the compositions after the tragic death of his wife in 2015. For the album, each member of the ensemble took on the task of arranging the pieces of music to create a cohesive piece of art under a unified theme. Mortality combined the conceptual aesthetics of progressive rock with the harmonic and tonal soundscapes of jazz and jazz improvisation. Despite the heavy subject matter the music on the album was delicate, melodic and hopeful.

Mortality was nominated for Jazz Album of the Year in 2020 in the Finnish equivalent of the Grammy Awards. Tapio also received a personal award, the Varjo-Yrjö, from the national broadcaster YLE for his outstanding work within the Finnish jazz community.

In addition to his own music Tapio has contributed his production and guitar playing talents to albums by artists like Mikko Löytty Bluestars, Jaakko Löytty, Juhani Valkama and Tammela 33100

Currently Ylinen is working on two new albums of original music. Fronting a new prog rock band 5th Season Ylinen will release an album in early 2023. Also in the works is the follow up album of instrumental music with the Mortality lineup.
