The recognition that a well-known image or logo affords a band cannot be disputed, nor should it be underestimated for the potential lucrative merchandising that follows. Consider, as a single example, Iron Maiden: their angular typeface has remained largely unaltered since the debut album back in 1980, and the image of Eddie has been synonymous with the band from day one. You can spot an Iron Maiden t-shirt or piece of merchandising from a goodly distance without necessarily knowing what tour or album it promotes, and this holds true for many other rock/metal bands including Motörhead, Cradle of Filth, Judas Priest, Metallica, et al.
Bands in the underground scene also rely on the strength of their image, and integral to that is the band logo. Nazgul is hardly an expert on the subject, but I can't immediately think of any other band that has had so many different ways of presenting its name/logo as Uruk Hai. Reinvention is not necessarily a bad thing, of course, and as these are not products generally found on the high street shelves the same brand-recognition doesn't perhaps come into play as strongly.
So let's take a ramble through a selection of Uruk Hai logos, past and present. This assortment does not pretend to be definitive, nor is it necessarily in strict chronological order, but it does capture a number of strikingly different examples from the 11 years history of the band.
1999 saw the release of Uruk Hai's "In Durin's Halls" demo, and with it a hand drawn band logo courtesy of Hugin. It resembles quite strongly the typeface of the Hrossharsgrani demo "Uruk Hai", which shouldn't be surprising as that was the demo that led to the ambient Uruk Hai project being formed. This curvy and fairly basic logo was used on the original "In Durin's Halls" demo tape and nowhere else thereafter.
