Last year the prolific Californian guitarist Ty Segall put out three albums. Another one is due later this year, under the band name Fuzz. It's hard to believe Segall ever sleeps. Having carved out a niche playing wild but catchy garage rock, Sleeper, his sixth album under his own name, finds Segall playing acoustic guitar, dealing with the death of his father and his broken relationship with his mother. It's no straightforward confessional, but a paradigm shift from squalling electricity to intensity of a different sort. Semi-electric songs like The Man Man still find time for baying-hounds solos, but his more psychedelic and folky sides are uppermost, never more so than on the duelling guitars (both Segall's) on 6th Street.
