Louis Michael James Stevens was born on 13 March 1942 in Solva, Pembrokeshire in west Wales,[1] to a non-conformist family.

From 1967 to 1969 he recorded a series of now rare Welsh-language picture sleeve EPs (Mike Stevens, Rhif 2 (Number 2), Mwg (Smoke), Y Brawd Houdini (The Brother Houdini); Meic Stevens, Diolch yn Fawr (Many Thanks), and Byw yn y Wlad (Living in the Country)).

Stevens played on recording sessions (notably for his friend Gary Farr's debut album on the Marmalade label).

He made a one-off English language LP, Outlander, for Warner Bros. Records in 1970, but the contract was abandoned by mutual consent.

In 1972 Gwymon (Wren Records) was released, an album containing some of his best known songs such as "Gwely Gwag" (Empty bed) and "Merch o'r Fatri Wlân."

In 1981, Stevens released a cassette of new songs, Cider Glider (The Farnham Sessions) in English, with the Cadillacs to accompany a return visit to Brittany.

This was followed by Gitâr Yn Y Twll Dan Star (Sain, 1983) that included songs from the lost rock opera Hirdaith A Craith Y Garreg Ddu.

Ware'n Noeth (Bi bop a lwla'r Delyn Aur) was recorded at Les Studio, Bethesda, and this was his first CD, released by Sain in 1991.

Ysbryd Solva (Spirit of Solva) (Sain) was released during the National Eisteddfod at St Davids in 2002, and Meic a'r Gerddorfa (Meic and the Orchestra) was recorded at the Brangwyn Hall in Swansea and the Ysgol Dyffryn Aman Hall in Ammanford with the BBC National Orchestra of Wales and released by Sain Records in 2005.

In 2011, Stevens announced that he wanted to migrate to Canada to join an old girlfriend, Liz, whom he met during his time as an art student in Cardiff in the early 1960s.

[5] Today Stevens' psych-folk influence can be heard in contemporary Welsh groups such as Super Furry Animals and Gorky's Zygotic Mynci, and his song "Cwm y Pren Helyg" was covered by Alun Tan Lan.
