Ultimate! is a comprehensive career retrospective album by English rock group the Yardbirds. The 52-song two–compact disc compilation was released in 2001 by Rhino Records. The tracks span the period from the group's first demo recordings in 1963 to the last singles in 1968. They include all 17 of the group's singles, both A-side and B-sides, supplemented with more than a dozen album tracks, their performance for the film Blow-Up, and three early solo numbers by singer Keith Relf.
The Yardbirds were one of the best-known British rhythm and blues groups of the mid-1960s and part of the British Invasion phenomenon in the United States. They enjoyed a string of Top 40 hits, including " For Your Love", " Shapes of Things", and " Over Under Sideways Down". Although one album appeared on the UK Albums Chart, they had greater success in the US, with six albums on the Billboard 200 album charts between 1965 and 1967.
A large number of compilation albums have been released over the years, usually limited to the group's pre-1966 catalogue. Attempts at full career retrospectives were hampered by cross-licensing problems. Yardbirds' recordings from different periods have different owners (corresponding to the tenures of their three main producers), which proved to be an obstacle. Ultimate! is the first official compilation to feature songs from all four recording lineups of the Yardbirds – including those with guitarists Eric Clapton, Jeff Beck, Jimmy Page, and the dual lead lineup with Beck and Page. The album was released to favourable reviews, with the critics describing it as the most comprehensive, but perhaps overinclusive, collection of the group's material.
