"Under Pressure" is a 1981 song by Queen and David Bowie. It marked Queen's first released collaboration with another recording artist, and is featured on their 1982 album Hot Space. The song reached #1 on the UK Singles Chart. It was also number 31 on VH1's 100 Greatest Songs of the 80s.Bowie had originally come to the studios in order to sing backing vocals in another Queen song, "Cool Cat," which would end up being edited out since he wasn't satisfied with them. Once he got there, they worked together for a while and wrote the song.In the song, Freddie Mercury sings the high vocals, and David Bowie sings the low ones.Queen had been working on the song under the title "Feel Like" but weren't yet satisfied with the result. The final version that became "Under Pressure" evolved from a jam session the band had with Bowie at its studio in Montreux, Switzerland, therefore it was credited as co-written by the five musicians. According to Queen bassist John Deacon (as quoted in a French magazine in 1984), however, the song's primary musical songwriter was Freddie Mercury — though all contributed to the arrangement. The earlier, embryonic version of the song without Bowie "Feel Like" is widely available in bootleg form. There has been some confusion about who created the song's famous bassline. John Deacon said (in Japanese magazine Musiclife in 1982, and in the previously mentioned French magazine) that David Bowie had created it. In more recent interviews, Queen guitarist Brian May and drummer Roger Taylor have credited the bass riff to Deacon; Bowie also said on his website that the bassline was already written before he became involved. The bassline may have an even earlier source -- it bears striking resemblance to the first theme of the third movement of Sibelius' first symphony of 1898. In any case, the September 2005 edition of online music magazine Stylus singled out the bassline as the best in popular music history. Under Pressure è una canzone dei Queen con David Bowie. È la prima collaborazione della band con un altro grande artista. La canzone sarà inserita poi nell'album Hot Space del 1982.Inizialmente Under Pressure non era nei piani della band e di Bowie, perché il cantante doveva solamente fare una voce nella canzone Cool Cat, sempre del disco Hot Space. Quando finirono le registrazioni Bowie non fu contento del risultato, così lui e Freddie Mercury decisero di scrivere il brano. Il ritmo del basso fu inizialmente attribuito a David Bowie, ma in un'intervista a Brian May e Roger Taylor, i due componenti dissero che l'idea fu di John Deacon. La canzone inizialmente fu chiamata People On Streets, ma poi variò in Under Pressure.Le versioni live del brano sono leggermente più veloci rispetto a quella originale.
