Online review by disharmoni (translated to English below)
At the end of the evening we quickly strolled to the Grand Hotel to catch the American band Sharp Pins, led by Chicago native Kai Slater. Slater looks like a real rock star and has clearly been raised on 60s jangle pop, which we can really appreciate, especially when he and the band are as skilled and well-played as they are.
By the way, before the concert we get a "warm-up band" that plays four songs, including "Rain" by The Beatles. It's the I Was A King members plus the legend Robyn Hitchcock, who with a twinkle in her eye claims that The Beatles were inspired by Oasis when they wrote "Rain".

A nice first day is over, and we stroll tired and weary up to the train station to get to Stavanger. We're looking forward to Saturday!
