A Boxful of Treasures is a 2004 compilation box set of recordings by folk rock legend Sandy Denny and comprises solo material and recordings made during her time as a member of Fotheringay, Fairport Convention, and other groups. The fifth CD contains previously unreleased tracks, most of which are demos recorded at Denny's home.

These historic recordings have every claim to be called the first British folk-rock album. 'All our own work' , comprising all original material, was recorded in Copenhagen in July 1967. Fairport Convention recorded their first album in November 1967 with Judy Dyble as their female singer; they did not start recording with Sandy Denny until June 1968. 'All our own work' has been shrouded in mystery for years. The sleeve-notes on the original release mistakenly claimed that the album was recorded in 1968. It was not released until 1973, to cash in on the Top Ten successes of Strawbs, and sold 65,000 copies. This new release dispels the myths. The booklet contains extracts from Dave Cousins diary with the full time-line; the original black and white sleeve photograph has been re-coloured; there are previously unheard songs. 'All our own work' contains the first recording of Sandy Denny's immortal 'Who knows where the time goes?' , which Judy Collins subsequently used as the title track of her 1968 album after hearing All our own work ! The first full CD release of the first British folk-rock album the complete sessions, remastered. 24 tracks - the original album, out-takes and demos plus three previously unreleased demos.

In the course of nine years, the Strawbs evolved from an obscure, quirky British bluegrass group into one of the most beloved progressive rock bands in the world. This 150-minute collection covers most of that history, encompassing most (but not all) of the key songs from their nine A&M albums, as well as lost B-sides, songs by ex-members Richard Hudson and John Ford, and a pair of tracks off of Dave Cousins' 1972 solo album Two Weeks Last Summer. The selection of material is inspired, juxtaposing rarities with a good deal of important music from the core of their output. The programming straddles the collectable and the historical/musical significance of the material, so we get early-'70s FM hits such as "The River" and "Down by the Sea" sharing space with material such as "Martin Luther King's Dream" and subsequent extended progressive material like "Ghosts." The range of styles is daunting, from Dylanesque acoustic folk-style numbers to extended songs in which Mellotrons, synthesizers, and loud, complex electric guitar runs are the dominant presences.

One of the better British progressive bands of the early '70s, the Strawbs differed from their more successful compatriots – the Moody Blues, King Crimson, Pink Floyd – principally in that their sound originated in English folk music rather than rock. Founded in 1967 as a bluegrass-based trio called the Strawberry Hill Boys by singer/guitarist Dave Cousins, the group at that time consisted of Cousins, guitarist/singer Tony Hooper, and mandolinist Arthur Phillips, who was replaced in 1968 by Ron Chesterman on bass.
