[3] Roma's equipment, at that point, consisted of a 1961 Gibson SG Special with Vibrola, a Lap steel guitar, a Sola Sound Fuzz, a Schaller Rotosound, a Wah-wah, a 4-track TEAC A-3340 and 2 Studer-Revox A77 tape machines.

[6][9] Allmusic reviewer Mark Richardson remarked that Inventions for Electric Guitar was reminiscent of fellow krautrockers Tangerine Dream's music from the same period, namely the Phaedra (1974) and Rubycon (1975) albums.

[5] On two of the French gigs, the new Ash Ra Tempel played alongside Cologne-based avant-rock group Can and Nico, of The Velvet Underground fame.

[5] On the 2010 edition of Japan's Metamorphose, one of the country's biggest outdoor electronic music festivals, Inventions was played for the first time live with 4 guitarists.

Beside Göttsching himself, the line-up included Steve Hillage, formerly of Gong and System 7, multi-instrumentalist Elliott Sharp and Zhang Shouwang of China's most prominent rock band, White.

Dubbed the "More Inventions for Electric Guitar" show, the set featured the entire 1975 album plus portions of E2-E4, considered by critics his masterpiece.
