Early releases focused on artists from Northampton (Religious Overdose, Where's Lisse & The Jazz Butcher), and the Midlands (Bron Area & In Embrace).

The label also issued material by Bauhaus member David J, and American punk band The Replacements, and the influential Liverpool Ur-grunge Walkingseeds.

A new imprint was announced in 2018, Glass Modern, ostensibly for new artists and vinyl reissues from cult figures from the international rock'n'roll underground, past, present and future.

The first six releases are by The Venus Fly Trap (Icon-GLAMCD001) The Froot (Forbidden Froot-GLAMCD002), on CD and Vinyl reissues by David J (Crocodile Tears and the Velvet Cosh-GLAMLP003), The Velvet Crush (In The Presence of Greatness-GLAMLP004), Thurston Moore (Klangfarbenmelodie.. And The Colorist Strikes Primitiv-GLALP006) and a brand New LP/Cd by David J in collaboration with Detroit PsychRockers Duende: Duende with David J (Oracle of the Horizontal-GLAMLP005/GLAMCD005) Albums may be in LP (GLALP, GLASSLP or GLEX), compact disc (GLACD or GLEXCD), or cassette (GLAMC or GLASSMC) format, with singles listed mainly with the GLASS prefix.

Artefacts with the same title under different catalogue entries refer to the same recording, if releases were not always issued in more than one format, leading to apparent gaps in the series.
