When Belgian rockers Triggerfinger released their eponymous debut in 2004, they were compared to the legendary Led Zeppelin by older listeners and Californian rock giants Queens of the Stone Age by younger fans. They certainly have their finger on the pulse of heavy rock, with a broad appeal that straddles the generational divide. Their hits teem with the urgent spirit of blues rock, and are peppered with fearsome rock ‘n' roll guitar riffs, while their albums take time to explore wider and often contemporary alt-rock elements, adding heavy metal and post-punk to their musical brew.
