After a short stint with Georgie Fame and the Blue Flames, a band he was to rejoin several times, he joined Brian Auger to become part of The Trinity,[1] and was soon followed by Long John Baldry.
The instrumental, "Beck's Bolero", with Jimmy Page on rhythm guitar, The Who's Keith Moon on drums, and bassist John Paul Jones; combined with Waller's playing on the remake of The Yardbirds' hit "Shapes of Things"; set the template for a heavier blues style.
In 1969, Waller flew to Venice Beach Los Angeles to form the band "Silver Metre" with guitarist Leigh Stephens of Blue Cheer fame, fellow Brit Pete Sears on bass and keyboards, and Jack Reynolds (singer).
They recorded one album at Trident Studios in London, England (one track, "Gang bang" containing an extended drum solo) which was released on the National General label,[6] produced by their manager, FM rock radio pioneer Tom Donahue.
The band included Ian Armitt on piano, and fellow Rod Stewart session men, Sam Mitchell on guitar, and Pete Sears on bass.
Over the intervening years Waller's playing experience included credits with The Walker Brothers, Cat Stevens, Eric Clapton, Bo Diddley, Dusty Springfield, Paul McCartney and Billy Bragg.
Upon his return to London, Waller briefly joined a revived Deluxe Blues Band that reunited him with Heckstall-Smith and Brunning, along with new members Dave Beaumont, Alan Vincent and Phil Taylor.
