And some System of a Down
The 1970s were Gallagher's most prolific period. He produced ten albums in that decade, including two live albums, Live In Europe and Irish Tour '74, which, for many, best captured his bands' raw and naturally dynamic qualities.. In 1972 he released the album Deuce, which is essentially three-piece R&B. Also in that year he was voted Melody Maker's Top Musician of the Year, ahead of Eric Clapton. Live In Europe has been commercially successful not only in Ireland, but also internationally.
Gallagher played and recorded what he said was "in me all the time, and not just something I turn on ...". Though he sold over thirty million albums world wide, it was his marathon live performances that won him greatest acclaim. His passion and skill for the blues is documented in the 1974 film Irish Tour '74, directed by Tony Palmer.
The line-up which included Rod De'Ath on drums and Lou Martin on keyboards, performed together between 1973 and 1978. Other release highlights from that period include Against the Grain, the jazz-tinged Calling Card album (assisted in production by Roger Glover (bassist with Deep Purple) and the hard blues-rock albums Photo Finish and Top Priority. Gerry McAvoy has stated that the Gallagher band performed several TV and radio shows across Europe, including Beat Club in Bremen and Old Grey Whistle Test. Along with Little Feat and Roger McGuinn, Gallagher performed the first Rockpalast live concert at the Grugahalle, Essen, Germany in 1977.
A dedicated follower of blues music, Gallagher played with many of the genre's biggest stars, collaborating with Muddy Waters and Jerry Lee Lewis on their respective London Sessions in the mid 70s. Gallagher was also invited to audition with The Rolling Stones following the departure of Mick Taylor and with Canned Heat after the departure of The Eagle. He was David Coverdale's second choice (after Jeff Beck) to replace Richie Blackmore in Deep Purple.
