"Acoustic Sessions" is a new Thin Lizzy album featuring stripped-back versions of Thin Lizzy classics and with previously unheard vocals provided by old recordings of late Phil Lynott. Not all material on the album is sourced from archived Thin Lizzy recordings though. Founding member Eric Bell has prepared fresh acoustic guitar arrangements for the new album, marking the first time since 1973 that Bell has played on a Thin Lizzy album.
