Switchfoot Oh! Gravity. (Columbia) Being a Christian band would automatically define a tight audience for most groups, but Switchfoot manage to play music that could offend only the most hardened atheist. There's no proselytising or songs about Jesus-inspired ecstasy. God isn't even mentioned - at least not directly. If you weren't aware of their religious background, you could quite easily listen to their music and never be the wiser. On Oh! Gravity., their sixth album, the five-man band at times offer a less annoying version of Coldplay, at others a softer take on Green Day. Their music is an upbeat and accessible blend of rock, grunge, indie, pop and punk rhythms. There's nothing groundbreaking here, but it does feature catchy choruses and smooth production by veteran British music man Tim Palmer, who has worked with top bands such as The Cure and U2. The lyrics show a reassuring depth and sensitivity considering that many of the tracks sound as if they could fit an American college movie soundtrack. Written by singer-guitarist Jonathan Foreman (who started the band with his bassist brother Tim in 1996), they touch on issues such as greed, the media, loss of innocence, politics and a lack of meaning in the modern world. The band's fourth album, The Beautiful Letdown, sold more than 2.6 million copies, and their latest is set to follow the same course. It entered the Billboard 200 albums chart at No18, and reached No1 on the iTunes Top Albums chart. Although some may be converted to their brand of good, earnest fun, Switchfoot are unlikely to ever inspire rapture.
