For Robin Trower, stage and studio are two sides of the same coin. If you've followed the seven-decade career of the award-winning British bluesman, you'll know every song on One Moment In Time: Live In The USA. But unless you've pushed your way to the front of his sell-out shows, you've never heard them like this before. "I'm a different player on the stage," considers the 80-year-old. "It's almost impossible to get to that point in the studio. It's the sound of the guitar, it's the volume, it's the crowd. For what I do, it takes one hundred per cent commitment for it to work. But if you do it well, it's life-affirming."
