The British quartet Syd Arthur inject their brand of space-warping indie rock with doses of late-'60s/early-'70s psychedelia, which makes their music sound as timeless as it is reverent.
If you took some late-'60s/early-'70s psychedelia, combined it with latter-day British-style indie rock and filter it through a mix of rock 'n' roll history, you'd get something like Syd Arthur.
