When they returned back to the US, the revue had a serious bus accident while on the road in Wichita, Kansas. A few band members were hospitalized, so Turner recruited members from St. Louis to continue the tour. By 1967, the revue started to book bigger venues in the United States. They performed a series of "exclusive deals" during this period, to help Ike increase their finances. As their careers were rising, their personal relationship was deteriorating and Tina attempted suicide before a show in 1968. In 1968, Bob Krasnow founded Blue Thumb Records, and Ike gave him enough masters for two albums. The first album, "Outta Season", was released in March 1969. It peaked at No. 43 on the "Billboard" R&B LP's chart. "Outta Season" produced the duo's cover of Otis Redding's "I've Been Loving You Too Long," which peaked at No. 23 on the R&B singles chart. In May 1969, Ike and the Kings of Rhythm released the album "A Black Man's Soul" on Pompeii Records. The album earned Ike his first solo Grammy nomination for Best R&B Instrumental Performance at the 12th Annual Grammy Awards. In August 1969, the duo headlined at International Hotel's Casino Theatre in Las Vegas. It was in Vegas that Ike, who up to that point had lived a drug and alcohol free life, began using cocaine. He recalled that he was introduced to the drug by "two famous Las Vegas headliners". In September 1969, A&M Records reissued the album "River Deep – Mountain High", and for the first time it was issued in the US. It was successful, reaching No. 28 on the R&B albums chart. The next month "The Hunter" was released on Blue Thumb, one of their most blues-oriented albums which features electric blues guitarist Albert Collins. The title track, "The Hunter," an Albert King cover, reached No. 37 in the R&B singles chart. The album peaked at No. 47 on the R&B albums chart, and earned Tina her first solo Grammy nomination for Best R&B Vocal Performance, Female at the 12th Annual Grammy Awards. As the 1960s came to an end, Ike and Tina began performing at rock festivals. In 1969 they performed at the Newport Pop Festival in Northridge and the Gold Rush Festival at Lake Amador. In October, they headlined the Soul Bowl at Tulane University's Sugar Bowl Stadium; a concert to raise money for disadvantaged minority students.
