While the band was recording the new album and touring in the UK, their managers at HEC Enterprises had found an agreement for Deep Purple to support
the Rolling Stones in their upcoming US tour during Spring 1969, the first in three years and a certain sold-out event. This time their trek also touched Canada, where their albums were distributed by
Polydor Records. this time the single "Emmaretta" and the band's back-catalogue remained sitting on store shelves. Coletta later commented on how 1969 was a wasted year for Deep Purple in America. Even though their most recent single was doing poorly, Deep Purple maintained a reputation as a fine live act in the US. Despite having turned into a highly proficient band on stage, things were starting to heat up internally, with band members getting more vocal about the direction they wanted the music to go, as well as being dissatisfied with their treatment financially. Simper remarked in later interviews, "Once we started making money, the friendships went out the window." He further noted that Blackmore was particularly peeved that Lord and Evans were earning royalties above and beyond the other band members because they had composed the B-side of the "Hush" single ("One More Rainy Day"). Meanwhile, Lord and Blackmore were tired of being identified as a "clone of
Vanilla Fudge" which had become a great success on both sides of the Atlantic, after its release in January 1969. They felt that Rod Evans, with his tender, smooth voice, would not be able to cope with louder, more aggressive material. Tensions were also high with bassist Nick Simper, On the other hand, Simper sided with Blackmore against Lord's excessive influence in the band's songwriting and was critical of classical music getting in the way of harder rock. As a result of those tensions, communication between band members was at a minimum during the tour. They talked their ideas over with drummer Paice, gaining his agreement to the line-up change.
End of the Mark I formation Back in England in early June, the decision taken had to be kept secret until the promotional tour for the British release of
The Book of Taliesyn was completed. Gillan, who did not see a future in his then current band, Gillan convinced the reluctant Glover to audition for Deep Purple and the two soon found themselves torn between the new band, which gladly welcomed both of them, and obligations with Episode Six for the completion of a UK tour. Evans, Simper and Episode Six's management were kept unaware of these events and of the fact that the new line-up was already active in writing and rehearsing new songs. Simper sued Deep Purple's management for breaking his contract, and the dispute was settled economically out of court. The music of the album
Deep Purple was played only during the tours of 1969 and never performed again by other line-ups, though Simper played songs from the first three Deep Purple albums with the tribute band Nasty Habits in Europe in 2010. ==Commercial and critical reception==
