Bowie met Angela Barnett in April 1969. They married within a year. Her impact on him was immediate, and her involvement in his career far-reaching, leaving manager Ken Pitt with limited influence which he found frustrating. Having established himself as a solo artist with "Space Oddity", Bowie began to sense a lacking: "a full-time band for gigs and recording—people he could relate to personally". The shortcoming was underlined by his artistic rivalry with Marc Bolan, who was at the time acting as his session guitarist. The band Bowie assembled comprised John Cambridge, a drummer Bowie met at the Arts Lab, Tony Visconti on bass and Mick Ronson on electric guitar. Known as Hype, the bandmates created characters for themselves and wore elaborate costumes that prefigured the glam style of the Spiders from Mars. After a disastrous opening gig at the London Roundhouse, they reverted to a configuration presenting Bowie as a solo artist. Their initial studio work was marred by a heated disagreement between Bowie and Cambridge over the latter's drumming style. Matters came to a head when an enraged Bowie accused the drummer of the disturbance, exclaiming "You're fucking up my album." Cambridge left and was replaced by Mick Woodmansey. Not long after, the singer fired his manager and replaced him with Tony Defries. This resulted in years of litigation that concluded with Bowie having to pay Pitt compensation.
