Steven Paul Smith was born at the Clarkson Hospital in Omaha, Nebraska, the only child of Gary Smith, a student at the University of Nebraska Medical Center, and Bunny Kay Berryman, an elementary school music teacher. His parents divorced when he was six months old, and Smith moved with his mother to Duncanville, Texas. Smith later had a tattoo of a map of Texas drawn on his upper arm and said: "I didn't get it because I like Texas, kind of the opposite. But I won't forget about it, although I'm tempted to because I don't like it there."
His first release, Roman Candle (1994), came about when Smith's girlfriend at the time convinced him to send a tape of "the most recent eight songs that [he'd] recorded on borrowed four-tracks and borrowed guitar" to Cavity Search Records. Owner Christopher Cooper immediately requested to release the entire album of songs, which surprised Smith, as he was expecting only a deal for a seven-inch record. Regarding the record, Smith said: "I thought my head would be chopped off immediately when it came out because at the time it was so opposite to the grunge thing that was popular ... The thing is that album was really well received, which was a total shock, and it immediately eclipsed [Heatmiser], unfortunately." Smith felt his solo songs were not representative of the music Heatmiser was making: "The idea of playing [my music] for people didn't occur to me... because at the time it was the Northwest--Mudhoney and Nirvana--and going out to play an acoustic show was like crawling out on a limb and begging for it to be sawed off." The instrumentation of the recordings was primarily acoustic guitar, occasionally accompanied by brief electric guitar riffs or a small drum set played with brushes. Only the final track, an instrumental titled "Kiwi Maddog 20/20" (a reference to the low-end fortified wine), had full band instrumentation. One of Smith's first solo performances was at the now-defunct Umbra Penumbra on September 17, 1994. Only three songs from Roman Candle were performed, with the majority of the ten-song set being B-sides, Heatmiser tunes and unreleased tracks. Soon after this performance, Smith was asked to open for Mary Lou Lord on a week-long U.S. tour. She later recorded one of his songs, "I Figured You Out", which he had discarded for sounding "too much like the Eagles". The same year, Smith released a split 7" single with Pete Krebs, contributing the track "No Confidence Man" as the single's B-side.

How many solo performances did smith have?

Mary Mary are an American gospel duo composed of sisters Erica Atkins-Campbell and Trecina Atkins-Campbell. Formed in 1998, Mary Mary was launched into mainstream recognition following the release of their best-selling debut album, Thankful (2000), which contained the hit single "Shackles (Praise You)". Their followup album Incredible (2002), reached number one on the Top Gospel Albums chart. Their third album, Mary Mary (2005), which contains themes the public interpreted as a channel to the group's experience, contains the worldwide hits "Heaven", "The Real Party", and "Yesterday".
The Atkins sisters, born Erica Monique and Trecina Evette, grew up in a large family with seven siblings in Inglewood, California. Their mother, Thomasina Atkins, is an evangelist and choir director at the Church of God in Christ. Their father, Eddie A. Atkins, was also a member of the Church of God In Christ, and a youth counselor, before he died in 2013. Due to their proximity in age, the two sisters grew up closer to one another than to any of their siblings: Darrell Atkins (born 1965, the only living boy- the second boy died as a child), Maliea Atkins (born 1967), Erica (born 1972), Tina (born 1974), Delisa Atkins-Brown (born 1977), Thomasina Atkins (born 1979), Alana Atkins-Jamison (born 1985), and Shanta Atkins (born 1986). Later, they would work creatively with over half of their siblings; Thomasina, Alana, Delisa and Shanta Atkins all sing background on Mary Mary's albums and during stage performances and Delisa was originally a member of the group but left before they started recording professionally due to pursuing college. Eventually, all eight Atkins children united on the Bobby Jones Gospel show on BET. During this time, Erica and Trecina entered the world of church choirs, traveling gospel shows, and television productions. The sisters enrolled at El Camino College to study voice. There they encountered the division between rigorous academic study of music versus the popular musical world. "We had to study classical and sing arias, which was fine," Erica told Times, "but the teachers would tell us if we sang anything else it would damage our instrument." In 1995 the two toured with Michael Matthews' traveling gospel shows, Mama I'm Sorry and Sneaky. Each sister subsequently toured as a backup singer for a variety of R&B acts, including Brandy.

Have any of the other siblings collaborated with them musically?
