Task: Question Answering
Input (English): Passage: Sons of Soul bridged the gap between commercial and critical success for Tony! Toni! Toné!, helping them become one of the most popular acts in R&B at the time. Its success exemplified the genre's commercial resurgence during the early 1990s, when hip hop became the predominant African-American music genre in the mainstream. In 1994, Greg Kot of the Chicago Tribune attributed its resurgence to younger artists' blend of live instrumentation and hip hop production values, and cited Sons of Soul as "the most accomplished merger of hip-hop attitude with a '70s R&B aesthetic." The Atlanta Journal-Constitution hailed it as "a gentle reminder of those glory days" and felt that the group having both vocal and musical talents is most indicative of a return to early R&B's aesthetics. Furthermore, they garnered mainstream attention in a year of several high-profile controversies with R&B and hip hop artists such as Michael Jackson and Snoop Dogg. David W. Brown of The Harvard Crimson wrote that Tony! Toni! Toné! is "known primarily for the quality of its music, not its extracurricular reputation, unlike other groups such as Jodeci who rely on a playa-gangsta-mack image to sell-records."Along with acts such as Mint Condition and R. Kelly, Tony! Toni! Toné! played live instruments that complemented their hip hop sensibilities. Their concerts featured visual elements such as incense smoke and kaleidoscopic stage lighting, the group's eccentric wardrobe, and additional instrumentalists, including another guitarist, two drummers, two keyboardists, a violinist, a trumpeter, and a saxophonist. The Charlotte Observer remarked on the group in 1994: "[T]heir use of live instruments on record and onstage makes them an anomaly in the synthesized and sampled world of modern R&B." With the group's reliance on traditional soul and R&B values of songwriting and instrumentation, Sons of Soul was a precursor to the neo soul movement of the 1990s. Matt Weitz of The Dallas Morning News wrote in 1993 that the group had distinguished themselves from their New jack swing contemporaries with Sons of Soul and found them aesthetically akin to acts such as Prince and P.M. Dawn. Raphael Wiggins said of their success with the album:
"We've been very blessed to be able to be a group that writes our own songs and people have accepted us from both sides, hip hop and the R&B crowd or whatever you might want to say. I feel very fortunate to be able to do that here in 1993–94, because like you know, it was starting to be a dying thing that was happening. But I guess we were like the bridge between hip hop and soul and R&B, and being a little bit commercial also helped us. A lot of humor, a lot of nice slow songs and being able to play kind of brought us a foundation.".
