In late January 1994, shortly before embarking on what would be their final European tour, Nirvana booked themselves into Robert Lang Studios in Seattle, Washington for three days. The band planned to record and work on new song ideas and went to Lang on the recommendation of drummer Dave Grohl, who lived nearby. Grohl and Krist Novoselic arrived on the afternoon of January 28th and expected Kurt Cobain to also show up at some point over the three days. Whilst they waited for him to arrive they took full advantage of the expensive studio time, recording some of their own material and experimental jams.
"It was just Krist and I screwing around with funny things like Skid Mark. And I recorded a couple of my songs. We just tried to make do with the time we had" Grohl later recalled. Most of the material recorded on the first two days was instrumental and given quick, working titles. After several instrumental jams (such as one experimenting with the sounds created by a Theremin plugged into an Echoplex tape machine) the pair recorded what was at the time simply labelled as 'Dave/Acoustic + Voc' . The track was in fact an early version of the song 'February Stars' according to Gillian G. Gaar who documented the session for a 2004 article in MOJO magazine.
Gaar also noted that the track featured alternative lyrics to those on the version later recorded and released on the Foo Fighters album 'The Colour And The Shape', in 1997. The song also featured Novoselic playing the Harmonium which according to guitar technician Earnie Bailey "really made the song".
By January 30th, with Cobain still not present, more of Dave's songs were recorded by he and Novoselic. Full versions of Exhausted' and 'Big Me' were recorded and were virtually identical to the versions Grohl later recorded for the Foo Fighters album, according to Gaar.
Cobain finally arrived at the studio on the afternoon of the 30th and Nirvana material was quickly recorded by the trio including 'You Know You're Right'. After this Cobain left but according to Gaar more material was recorded by Grohl and Novoselic including a rough instrumental version of the track 'Butterflies'.
