hop near the peak of its popularity, with artists such as Howie B and Earthling making significant contributions. Ninja Tune, the independent record label founded by the Coldcut duo, would significantly influence the trip-hop sound in London and beyond with breakthrough artists DJ Food, 9 Lazy 9, Up, Bustle & Out, Funki Porcini and The Herbaliser, among others. The period also marked the debut of two acts who, along with Massive Attack, would define the Bristol scene for years to come. In 1994, Portishead, a trio comprising singer Beth Gibbons, Geoff Barrow, and Adrian Utley, released their debut album Dummy. Their background differed from Massive Attack in many ways: one of Portishead's primary influences was 1960s and 1970s film soundtrack LPs. Nevertheless, Portishead shared the scratchy, jazz-sample-based aesthetic of early Massive Attack (whom Barrow had briefly worked with during the recording of Blue Lines), and the sullen, fragile vocals of Gibbons also brought them wide acclaim. In 1995, Dummy was awarded the Mercury Music Prize as the best British album of the year, giving trip-hop as a genre its greatest exposure yet. Portishead's music, seen as cutting edge in its film-noir feel and stylish, yet emotional appropriations of past sounds, was also widely imitated, causing the band to recoil from the trip-hop label they had inadvertently helped popularize, with Barrow stating "The whole trip-hop tag was nonsense. It was developed by people in London, and the people in Bristol just had to put up with it.". Tricky also released his debut solo album Maxinquaye in 1995, to great critical acclaim. The album was produced largely in collaboration with Mark Saunders. Tricky employed whispered, often abstract stream-of-consciousness murmuring, remote from the gangsta-rap braggadocio of the mid-1990s US hip hop scene. Even more unusually, many of the solo songs on Maxinquaye featured little of Tricky's own voice: his then-lover, Martina Topley-Bird, sang them, including her reimagining of Public Enemy's militant 1988 rap "Black Steel in the Hour of Chaos", while other songs were male-female duets dealing with sex and love in oblique ways, over beds of sometimes dissonant samples. Within a year Tricky had released two more full-length albums which were considered even more challenging, without finding the same popularity as his Bristol contemporaries Massive Attack and Portishead. Through his brief collaborations with Björk, however, he also exerted influence closer to the pop and alternative rock mainstream, and he developed a large
